We consider electroweak corrections to Higgs boson pair production, taking into account the top quark Yukawa and Higgs boson self couplings. Using differential equations we compute a deep expansion of all master integrals in the high-energy limit and present analytic results for the two-loop box-type form factors. We show that precise numerical results can be obtained even for relatively small values of the Higgs boson transverse momentum. We compare against recent numerical results and find good agreement.

We study the conformal field theory data (CFT-data) of planar 4D ( mathcal{N} ) = 4 Super-Yang-Mills theory in the strong ’t Hooft coupling limit. This regime explores the physics of massive short strings in the flat-space limit of the dual AdS. We focus on the CFT-data of the massive short strings exchanged in the operator product expansion (OPE) of the four-point function dual to the Virasoro-Shapiro amplitude. This CFT-data arranges itself into Regge trajectories in the flat-space limit. Using inputs from recent advances in the computation of the AdS Virasoro-Shapiro amplitude, integrability, and a stipulation based on analyticity of the CFT-data in spin, we are able to fix all the CFT-data on the four unique sub-leading Regge trajectories, at leading non-trivial order, as a function of the string-mass level. One of our predictions is that one of the four unique sub-leading Regge trajectories decouples from the OPE in the flat-space limit. This hints at an emergent selection rule in the flat-space limit, similar to our previous results in arXiv:2310.06041. Our procedure should be applicable in a variety of similar setups like for the AdS Veneziano amplitude or in ABJM.

Recent breakthrough experiments have demonstrated how it is now possible to explore the dynamics of quantum Hall states interacting with quantum electromagnetic cavity fields. While the impact of strongly coupled nonlocal cavity modes on integer quantum Hall physics has been recently addressed, the effects on fractional quantum Hall (FQH) liquids—and, more generally, fractionalized states of matter—remain largely unexplored. In this work, we develop a theoretical framework for the understanding of FQH states coupled to quantum light. In particular, combining analytical arguments with tensor network simulations, we study the dynamics of a ν=1/3 Laughlin state in a single-mode cavity with finite electric field gradients. We find that the topological signatures of the FQH state remain robust against the nonlocal cavity vacuum fluctuations, as indicated by the endurance of the quantized Hall resistivity. The entanglement spectra, however, carry direct fingerprints of light-matter entanglement and topology, revealing peculiar polaritonic replicas of the U(1) counting. As a further response to cavity fluctuations, we also find a squeezed FQH geometry, encoded in long-wavelength correlations. By exploring the low-energy excited spectrum inside the FQH phase, we identify a new neutral quasiparticle, the graviton polariton, arising from the hybridization between quadrupolar FQH collective excitations (known as gravitons) and light. Pushing the light-matter interaction to ultrastrong-coupling regimes, we find other two important effects, a cavity vacuum-induced Stark shift for charged quasiparticles and a potential instability toward a density modulated stripe phase, competing against the phase separation driven by the Stark shift. Finally, we discuss the experimental implications of our findings and possible extension of our results to more complex scenarios. Published by the American Physical Society2025

We explore the distribution in space and time of a single-photon excitation shared by a network of dipole–dipole interacting atoms that are also coupled to a common photonic field mode. Time-averaged distributions reveal partial trapping of the excitation near the initially excited atom. This trapping is associated with resonances of the excitation at crossing points of the photon-dressed energy eigenvalues of the network. The predicted photon-induced many-atom trapped excitation (PIMATE) is sensitive to atomic position disorder which broadens the excitation resonances and transforms them to avoided crossings. PIMATE is shown to allow highly effective and accurate sensing of multi-atom networks and their disorder.

The rigorous conditions for obtaining sensible predictions in non (proper) renormalizable quantum field theories were derived a long time ago, most notably in the works of Steven Weinberg. In this paper we explicitly illustrate the challenges met in carrying this program within the affine gravity framework, in particular when attempting to pinpoint viable particle propagation. We explore the one-loop structure of some ghost and tachyon-free vector theories to illustrate the role of structural constraints in their interactions, even in the absence of gauge symmetries. Despite the presence of soft-breaking terms, we show how hopes of casting a vector model within the predictive frame of effective field methods hinges on adopting a gauge-like treatment of their interactions. Our focus here is restricted to negative results and no-go theorems, while a forthcoming companion paper will explore viable examples and constructive scenarios.

Vehicle interior noise significantly affects passenger comfort and is composed of powertrain, road, and aerodynamic noise—the latter becoming dominant at high speeds. Advances in noise control and the rise of electric vehicles have diminished engine noise, thereby accentuating aerodynamic noise, which typically spans a frequency range of 40 Hz to 5 kHz. To address the challenges posed by this broadband, nonlinear noise, we propose a Hybrid Aerodynamic Active Noise Control (HAANC) methodology that integrates advanced signal processing and machine learning for precise noise suppression. Specifically, Variational Mode Decomposition (VMD) and the Hilbert-Huang Transform (HHT) are employed for high-resolution signal decomposition and feature extraction, while an adaptive multi-filter structure enhances computational efficiency and stability. In addition, a novel signal extraction network—built on convolutional and bidirectional long short-term memory layers with an attention mechanism—is designed to preserve in-vehicle target sounds, such as conversations and music, amidst interference. Experimental evaluations on real-world datasets show that for pure aerodynamic noise signals, Normalized Mean Squared Error (NMSE) decreased by approximately 10.23 dB and the power spectral density (PSD) was reduced by an average of 15.6 dB/Hz. Under mixed-signal conditions with a –10 dB signal-to-noise ratio, short-time objective intelligibility (STOI) improved by 6.2 %, Perceptual Evaluation of Speech Quality Mean Opinion Score (PESQ MOS) increased by 26.28 %, and Mean Opinion Score Listening Overall Opinion (MOS LOO) increased by 27.42 %. These quantitative improvements substantiate the superior performance and generalization capabilities of the proposed HAANC system for enhancing passenger comfort.

We discuss selection rules of chiral matters in type IIA intersecting and IIB magnetized D-brane models on toroidal orbifolds. Since the chiral matters on toroidal orbifolds are labeled by a certain conjugacy class of the gauged orbifold group, the selection rules involve non-trivial fusion rules. We find that the representation of the chiral matters is described by a D4 flavor symmetry for an even number of magnetic fluxes or winding numbers at tree level. Furthermore, the D4 symmetry still remains even when we take into account loop effects. We also study non-perturbative effects such as D-brane instantons.

Homogeneity is the hallmark of standard candle-based cosmology investigations. Thermonuclear supernovae (Type-Ia, SNeIa) violate this essential requirement if they develop along multiple evolutionary pathways. In this work, the impact of thermonuclear diversity on cosmological parameter constraints is quantified using Pantheon+, one of the largest ensembles of SNeIa compiled to probe cosmology to date. Evidence of diversity is encoded in supernova light curves. Pantheon+ is shown to be diverse, with features indicative of multiple thermonuclear subclasses. Diversity driven systematic effects have been quantified on a supernova-by-supernova basis; event selections based on light curve derived metrics were subsequently used to characterize diversity dependent trends and limit their impact.

General relativity predicts the presence of a singularity inside of a black hole revealing that it is not a complete theory of gravity. A real structure of a black hole interior near an expected singularity depends on the UV completion of gravity. In this paper we address the question of whether singular spherically symmetric solutions are absent (or present) in a complete gravity theory. We find that the answer is governed by the functional form of a nonperturbative graviton propagator. A ghost-free infinite derivative gravity is favored by the unitarity the graviton propagator of an exponential form. We explicitly show in this framework that a singularity is not possible unless an unphysical situation when a mass of the black hole is infinite is considered.

We extend the catalogue of “phenomenologically preferred” hadronic axion models to include heavy fermion representations associated with higher-dimensional decay operators. The latter have recently been shown to self-consistently trigger a period of early matter domination, making the underlying axion models cosmologically viable. After identifying all possible representations up to decay operator dimension d ≤ 9, we update the hadronic axion band for the axion-photon coupling. The central regions of the axion band are similar to those found previously and approximately independent of the axion decay constant fa, suggesting that they are robust predictions and targets for future axion searches. Moreover, we find that d = 6 and d = 7 operators can lead to two new viable “model islands” around fa ∼ 1012 GeV and fa ∼ 1014 GeV, i.e., beyond the standard post-inflationary mass region.
