TL;DR: In this paper, the authors consider invariance under the finite modular group Γ 4 ≃ S 4 and focus on the minimal scenario where the expectation value of the modulus is the only source of symmetry breaking, such that no flavons need to be introduced.

TL;DR: In this paper, a version of the Weak Gravity Conjecture for 6d F-theory or heterotic string compactifications with 8 supercharges is presented, where the extremality condition of a charged black hole is modified and the test particles required to satisfy the weak gravity conjecture are subject to additional Yukawa type interactions.

TL;DR: In this article, the authors consider a full basis of gauge-invariant dimension-six operators involving SM fermions and right-handed singlet neutrinos and map their Wilson coefficients onto GNI parameters.

TL;DR: In this article, a review of the experimental observations from the ALICE Collaboration at the Large Hadron Collider (LHC) is presented, with a focus on the production of (anti-)nuclei and (anti-hypernucleus) and a possible bound state of a Λ hyperon and a neutron.

TL;DR: In this paper, the authors present a method to compute the unified flavor symmetry of the low-energy effective theory, including enhancements from the modular transformations of string theory, which is non-universal in moduli space and exhibits the phenomenon of local flavor unification.

TL;DR: In this paper, the authors studied Lorentz-invariant, infinite derivative quantum field theories, where infinite derivatives give rise to non-local interactions at the energy scale M s, beyond the Standard Model.

TL;DR: In this paper, the elastic I = 1 p-wave ππ scattering amplitude is calculated together with the isovector timelike pion form factor using lattice QCD with N f = 2 + 1 dynamical quark flavors.

TL;DR: An algorithm which allows to solve analytically linear systems of differential equations which factorize to first order in terms of iterated integrals over an alphabet where its structure is implied by the coefficient matrix of the differential equations is presented.

TL;DR: In this article, the authors derived the expressions for the full angular distributions of pseudoscalar to vector meson decay and discussed the spectra on each angle separately, and examined the sensitivity of each of these observables on the presence of non-Standard Model interaction terms at low energies.

TL;DR: In this paper, a particular lattice discretization of abelian gauge theories in arbitrary dimensions is discussed, based on gauging the center symmetry of a non-compact ABG theory, which results in a Villain type action.

TL;DR: Author(s): Niida, Takafumi; Adam, J; Adamczyk, L; Adams, JR; Adkins, JK; Agakishiev, G; Aggarwal, MM; Ahammed, Z; Alekseev, I; Anderson, DM; Aoyama, R; Aparin, A; Arkhipkin, D; Aschenauer, EC; Ashraf, MU; Atetalla, F

TL;DR: For string theory on AdS3 with pure NS-NS flux, a complete set of DDF operators is constructed, from which one can read off the symmetry algebra of the spacetime CFT as mentioned in this paper.

TL;DR: In this paper, a unified F ( R, G ) gravity model is proposed, in which the early and late time dynamics are controlled by the F(R,G ) gravity, thus producing inflation and the dark energy era, while the intermediate era is approximately identical with standard EH.

TL;DR: In this paper, a general study of 3-point functions of conformal field theory in momentum space is presented, following a reconstruction method for tensor correlators, based on the solution of the conformal Ward identities (CWI's), introduced in recent works by Bzowski, McFadden and Skenderis (BMS).

TL;DR: In this article, the authors conjecture the universality of eigenstate entanglement by proposing an exact formula for its dependence on the subsystem size, derived from an analytical argument based on a plausible assumption, and supported by numerical simulations.

TL;DR: A new search strategy for phenomenologically promising string models is proposed using deep autoencoder neural networks to draw a chart of the heterotic Z 6 -II orbifold landscape and applies a decision tree to this chart to extract the defining properties of the fertile islands.

TL;DR: The first law of thermodynamics in the non-extremal Reissner-Nordstrom anti-de Sitter black hole is recovered by the scattering of the scalar field as discussed by the authors.

TL;DR: This investigation provides a first significant step in the direction of devising robust tools for quantitative analyses of phase transitions in cases in which an order parameter is not known.

TL;DR: In this article, it was shown that the Reissner-nordstrom-de Sitter (RNdS) black holes are globally hyperbolic and therefore respect the strong cosmic censorship conjecture.

TL;DR: In this article, the effect of Lorentz symmetry breaking (LSB) on the Hawking radiation of Schwarzschild-like black hole found in the bumblebee gravity model (SBHBGM) is studied in the framework of quantum gravity.

TL;DR: In this paper, the six-loop expansions of the renormalization-group functions of φ 4 n-vector model with cubic anisotropy are calculated within the minimal subtraction (MS) scheme in 4 − e dimensions.

TL;DR: In this paper, the authors presented the first lattice-QCD calculation of the kaon distribution amplitude using the large-momentum effective theory (LaMET) approach.

TL;DR: In this paper, the authors studied string theory in the background M 3 that interpolates between A d S 3 in the IR and linear dilaton spacetime R 1, 1 × R ϕ in the UV.

TL;DR: In this article, a connection 1-form, ϖ, is introduced in the field-space of Yang-Mills theory, and a modified version of symplectic geometry is possible.

TL;DR: In this paper, the microscopic character of a hairy black hole of Einstein's theory conformally coupled to a scalar field in five dimensions by means of the Ruppeiner thermodynamic geometry is explored.

TL;DR: In this paper, the authors studied the holographic description of N = 2 super conformal field theories in four dimensions first given by Gaiotto and Maldacena and presented new expressions that holographically calculate characteristic numbers of the CFT and associated Hanany-Witten set-ups.

TL;DR: In this paper, a series of papers dedicated to the study of the partition function of three-dimensional quantum gravity on the twisted solid torus with the aim to deepen our understanding of holographic dualities from a non-perturbative quantum gravity perspective is presented.

TL;DR: In this article, a detailed analysis of the current-current correlation function for the conductivity tensor was carried out, initially in the Chalker-Coddington network model for the IQHE plateau transition and then in its exact reformulation as a supersymmetric vertex model.

TL;DR: In this article, the authors consider the deformation of a generic d-dimensional large-N CFT on a sphere by a spin-0 operator which is bilinear in the components of the stress tensor.
