Bi-scalar CFT from [Formula: see text] deformed [Formula: see text] SYM describes the fishnet theory which is integrable in the planar limit. The holographic dual of the planar model is the fishchain model. The derivation of the weak–strong duality from the first principle was presented in a recent paper (“The Holographic Fishchain” arXiv:1903.10508). In this paper, we extend the investigation to the tri-scalar CFT which arises from the large twist limit of ABJM theory. We show that it becomes tri-scalar fishnet theory in planar limit and the dual theory is the holographic bi-fishchain model.

This paper presents a method for extracting the parton distribution functions (PDFs) at small momentum fractions [Formula: see text] and at the next-to-leading order (NLO) accuracy in perturbative quantum chromodynamics. It turns out that the PDFs can be described by the “Fractal” or self-similar distributions at low [Formula: see text] below [Formula: see text]. To this end, a simple parametrization for the unintegrated PDFs based on the “Fractal” approach is considered. These functions have self-similar behavior at low [Formula: see text] and [Formula: see text] for sea quarks and have self-similar behavior at low [Formula: see text] for gluon distribution. By integration from these transverse momentum distributions (TMDs), the initial input densities are obtained and the model’s free parameters are then calculated using the experimental data released by the HERA experiment. The small-[Formula: see text] experimental datasets on electron–proton ([Formula: see text]) and positron–proton ([Formula: see text]) for natural current (NC) interactions in deep inelastic scattering (DIS) processes at HERA for the range of [Formula: see text] (GeV 2 ) and [Formula: see text] are included in this analysis. The uncertainty estimations in this analysis are carried out using the standard “Hessian” method. Considering the overall value of [Formula: see text] and theory-to-data comparisons, the results indicate good agreements between the experimental datasets and the theoretical predictions. A detailed comparison is also presented between the model’s predictions for the relevant small-[Formula: see text] observable and recent parametrizations for the PDFs.

There is a formulation of unimodular gravity (UG) in which the unimodular metric is obtained out of an unrestricted one as γ µν “ | g | ´ 1 n g µν . This unrestricted metric is only defined up to a Weyl rescaling. Physical charges like ADM energy or horizon entropy, however, are not Weyl invariant in general. In this paper a Weyl invariant definition of some physical charges is given, and the results are illustrated for the Painlev´e-Gullstrand extension of Schwarzschild spacetime
存在一个关于幺模引力（UG）的公式，其中从一个不受限制的度量中得到了幺模度量γ“|g|´1 n gµΓ。这个不受限制的度量只能定义为Weyl重缩放。然而，像ADM能量或视界熵这样的物理电荷通常不是Weyl不变量。本文给出了一些物理电荷的Weyl不变性定义，并举例说明了Schwarzschild时空的Painlev´e-Gullstrand扩展的结果

We consider the Schrödinger equation with a generalized form of uncertainty principle and solve the problem up to a third-order correction to the arising equation. The particle in box and harmonic oscillator cases are considered in this formulation and various thermodynamic properties are reported including entropy, internal energy, chemical potential, specific heat, etc. Various consequences of the GUP are commented.
