Astrophysical uncertainties in dark matter direct detection experiments are typically addressed by parametrizing the velocity distribution in terms of a few uncertain parameters that vary around some central values. Here we propose a method to optimize over all velocity distributions lying within a given distance measure from a central distribution. We discretize the dark matter velocity distribution as a superposition of streams and use a variety of information divergences to parametrize its uncertainties. With this, we bracket the limits on the dark matter–nucleon and dark matter–electron scattering cross sections, when the true dark matter velocity distribution deviates from the commonly assumed Maxwell-Boltzmann form. The methodology pursued is general and could be applied to other physics scenarios where a given physical observable depends on a function that is uncertain.

暗物质直接探测实验中的天体物理不确定性通常是通过将速度分布参数化来解决的,这些参数在一些中心值周围变化。在这里,我们提出了一种方法,以优化所有的速度分布位于一个给定的距离测量中心分布。我们将暗物质速度分布离散为流的叠加,并使用各种信息散度来参数化其不确定性。有了这个,当真正的暗物质速度分布偏离通常假设的麦克斯韦-玻尔兹曼形式时,我们将暗物质-核子和暗物质-电子散射截面的极限包围起来。所采用的方法是通用的,可以应用于其他物理场景,其中给定的物理观测取决于不确定的函数。2025年由美国物理学会出版

本文通过在颜色空间中构造约化密度矩阵ρ,研究了T=0时约束相中伴随胶子激发的静态夸克和反夸克(qq¯)之间的颜色相关性。采用标准Wilson规范作用的库仑规进行了猝灭晶格量子色动力学(QCD)计算,在β=5.8时,空间体积为L3=323,对应于晶格间距a=0.14 fm,系统体积L3=4.53 fm3。我们评估了6个通道(Σg+, Σg+ ‘, Πu, Πu ’, Δg, Δg ')中静态qq¯对的颜色密度矩阵ρ,并研究了颜色相关性的夸克-距离依赖关系。我们发现,在有和没有胶子激励的qq¯系统中,随着夸克间距离的增加,颜色相关因颜色泄漏到胶子场而猝灭,最终趋于随机颜色组态。对于这种颜色屏蔽效应,我们评估了“屏蔽质量”,讨论了它与胶子激发的量子数通道的依赖关系。2025年由美国物理学会出版

This article presents constraints on dark-matter-electron interactions obtained from the first underground data-taking campaign with multiple SuperCDMS HVeV detectors operated in the same housing. An exposure of 7.63g−days is used to set upper limits on the dark-matter-electron scattering cross section for dark matter masses between 0.5 and 1000 MeV/c2, as well as upper limits on dark photon kinetic mixing and axionlike particle axioelectric coupling for masses between 1.2 and 23.3 eV/c2. Compared to an earlier HVeV search, sensitivity was improved as a result of an increased overburden of 225 meters of water equivalent, an anticoincidence event selection, and better pile-up rejection. In the case of dark-matter-electron scattering via a heavy mediator, an improvement by up to a factor of 25 in cross section sensitivity was achieved. Published by the American Physical Society 2025
本文介绍了在同一外壳内运行的多个SuperCDMS HVeV探测器的第一次地下数据采集活动中获得的暗物质-电子相互作用的约束。7.63g−days的曝光量被用来确定暗物质质量在0.5 ~ 1000 MeV/c2之间的暗物质-电子散射截面上限,以及质量在1.2 ~ 23.3 eV/c2之间的暗光子动力学混合和类轴子粒子轴电耦合的上限。与早期的HVeV搜索相比,由于覆盖层增加了225米水当量,反巧合事件选择和更好的堆积抑制,灵敏度得到了提高。在通过重介质的暗物质-电子散射的情况下,在截面灵敏度上提高了25倍。2025年由美国物理学会出版

We investigate the nonlinear stability of global anti–de Sitter space in the presence of multitrace deformations utilizing an Einstein-Klein-Gordon system with a top-down scalar potential. Our numerical simulations show that marginal and irrelevant deformations retain the nonlinear instability originally found by Bizoń and Rostworowski, while relevant deformations disrupt it. We show that the nonlinear impact of multitrace deformations is in one-to-one correspondence with how they affect the resonant character of the global anti–de Sitter normal mode eigenfrequency spectrum.

Tensor network methods have demonstrated their suitability for the study of equilibrium properties of lattice gauge theories, even close to the continuum limit. We use them in an out-of-equilibrium scenario, much less explored so far, by simulating the real-time collisions of composite mesons in the lattice Schwinger model. Constructing wave-packets of vector mesons at different incoming momenta, we observe the opening of the inelastic channel in which two heavier mesons are produced and identify the momentum threshold. To detect the products of the collision in the strong coupling regime we propose local quantitites that could be measured in current quantum simulation platforms.

We train a deep neural network (DNN) to output rates of dark matter (DM) induced electron excitations in silicon and germanium detectors. Our DNN provides a massive speedup of around 5 orders of magnitude relative to existing methods (i.e., dark-), allowing for extensive parameter scans in the event of an observed DM signal. The network is also lighter and simpler to use than alternative computational frameworks based on a direct calculation of the DM-induced excitation rate.

We discuss the nonlocal generalization of the QCD chiral anomaly along the light cone and derive relations between twist-two, twist-three, and twist-four generalized parton distributions (GPDs) mediated by the anomaly. We further establish the connection to the “anomaly pole” in the GPD E˜ recently identified in the perturbative calculation of the Compton scattering amplitudes, and demonstrate its cancellation at the GPD level. Our work helps elucidate the previously unexplored connection between GPDs, the chiral anomaly, and the mass generation of the η meson. Published by the American Physical Society 2025

In this paper we investigate the code properties of holographic fractal geometries initiated in Pastawski []. We study reconstruction wedges in AdS3/CFT2 for black hole backgrounds, which are in qualitative agreement with the vacuum-AdS approximation using generalized entanglement entropy in Bao []. In higher dimensions, we study reconstruction wedges for the infinite, straight strip in AdSd+1/CFTd and clarify the roles of “straight” and “infinite” in their code properties. Lastly, we comment on uberholography from the perspective of complexity transfer and one-shot holography. Published by the American Physical Society 2025

Antiquark nuggets are hypothetical compact composite objects conjectured to account for a significant fraction of dark matter in the Universe. In contrast to quark nuggets, these objects consist of antimatter. They may remain undetected if they possess a sufficiently small cross section relative to their mass. In this paper, we investigate the allowed region in the parameter space of this model that is consistent with the observed neutrino flux from the Sun and the Earth, and the nonobservation of seismic events with specific signatures of dark matter particles. We found the allowed values of the antibaryon charge number in this model to be in the interval 2×1024<A<8×1025, while the probability of nucleon annihilation upon collisions with the antiquark core is constrained by 0.1κ<0.25. These values of A and κ are, however, constrained by the IceCube experiment and nonobservation of impacts of antiquark nuggets on humans. Although very large values of the antibaryon charge, A>1033, are not fully excluded by the present study, we show that they conflict with the nonobservation of rare catastrophic explosionlike events on the Earth.

反夸克块是一种假想的致密复合物体,据推测它占宇宙暗物质的很大一部分。与夸克块相反,这些物体是由反物质组成的。如果它们的横截面相对于它们的质量足够小,它们可能不会被发现。本文研究了该模型参数空间中与观测到的来自太阳和地球的中微子通量相一致的允许区域,以及未观测到具有暗物质粒子特定特征的地震事件。我们发现该模型中反重子荷数的允许值在2×1024<;A<;8×1025区间内,而核子与反夸克核碰撞后湮灭的概率受0.1≤κ<;0.25的约束。然而,这些A和κ的值受到冰立方实验和未观察到反夸克块对人类的影响的限制。虽然反重子电荷的非常大的值,A>1033,并没有被本研究完全排除,但我们表明,它们与地球上罕见的灾难性爆炸事件的未观测相冲突。2025年由美国物理学会出版
