Summary: There are currently two singularity-free universal expressions for the topological susceptibility in QCD, one based on the Yang-Mills gradient flow and the other on density-chain correlation functions. These two expressions are shown to coincide in the continuum theory, providing insight into the emergence of topological sectors in lattice QCD.

Summary: This passage discusses the conservation of an axial current modified by the gravitational chiral anomaly, which implies a universal transport phenomenon (kinematical vortical effect) dependent solely on medium vorticity and acceleration, regardless of its temperature and density. This general analysis is verified for the case of massless fermions with spin -1/2.

Summary: This study explores coupling dependent gravitational waves generated during the cosmic first-order QCD phase transition at finite baryochemical potential. The research finds that gravitational waves may be detected under sufficiently large Gauss-Bonnet coupling, and also considers a supercooling scenario during the QCD phase transition where gravitational waves can be detected by future experiments.

Summary: The Nonminimal Derivative Coupling (NDC) is an alternative to General Relativity, which offers an inflationary mechanism in cosmology. The detection of gravitational waves has posed strict constraints on gravitational theories, leading to a revision of such theories to investigate their compatibility with observational data. This paper reviews the NDC and examines its compatibility with gravitational waves, finding that the existence of gravitational waves is limited in phase space and there are no accelerated solutions compatible with current data. This is partly due to the lack of detection of primordial gravitational waves.

Summary: Novel features of n-dimensional spacetimes sourced by a massless (non) phantom scalar field in general relativity are discussed, including a complete classification of static solutions and the existence of parallelly propagated curvature singularities. The study also reveals the presence of regular wormholes in two-sided asymptotically flat spacetime and presents a comprehensive classification of solutions coupled to a conformal scalar field.

Summary: This paper discusses the universality of the renormalization of the gauge coupling constant in quantum electrodynamics coupled to Einstein's gravity in arbitrary gauge within the framework of effective field theory. Despite different contributions from the gravitational sector to the renormalization of three-point functions with different particles, the universality of the gauge coupling constants is guaranteed by the Ward identity, ensuring that the renormalized electric charge receives no contribution from the gravitational sector at one-loop order.

Summary: This article briefly reviews the essential aspects of the QCD instanton vacuum in relation to the quantum breaking of conformal symmetry, the spontaneous breaking of chiral symmetry, and the axial U(1) anomaly. The intrinsic nucleon spin transmutes to the vacuum topological charge through the anomaly by quantum tunneling. Using Ji's invariant spin decomposition, we discuss the spin budget of the nucleon as a quark-diquark state in the QCD instanton vacuum.

Summary: Two simple ways to deplete the standard signals of the Standard Model Higgs boson are discussed: by suppressing its couplings and draining part of its branching fraction into invisible final states. The presence of additional scalar bosons that mix with the Higgs boson can impose these depletion factors. The study explores the present status and future prospects for detecting the depleted Higgs boson and provides insights into the constraints and detection prospects for extra mixed-in scalars.

It finds that the deconfinement temperature decreases with increasing rotation, and the results are consistent with previous studies.

Summary: In this study, results for SCET and bHQET matching coefficients and jet functions are presented in the large-beta(0) limit. The computations accurately predict terms of a specific form and are in full agreement with the coefficients obtained in the full theory up to a certain order of approximation. Closed expressions for anomalous dimensions and matrix elements are obtained, which can be expanded to higher powers of alpha(s) using recursive algorithms. The perturbative convergence of a series and the size of non-perturbative corrections are quantified by examining the poles on the Borel-transform variable u.

Summary: Theories with generalised conformal structure exhibit similar properties to conformal field theories in lower dimensions, where the standard normalization constant is replaced by a function of the effective coupling constant g constructed from dimensionful parameters and the separation of operators. These theories play a role in holographic dualities involving non-conformal branes, and the phi(6) coupling, while irrelevant in the context of generalised conformal structure, has effects in the UV regime.

Summary: The study explores the boosted dark matter solution of the XENON1T excess, constraining the framework through loop-generated processes. The effective coupling of the boosted dark matter component with electrons makes it potentially visible in electron recoil searches, and it also becomes observable in nuclear recoil measurements once radiative corrections due to the Standard Model are considered. Analysis in effective models built on vector and scalar couplings shows that current direct detection constraints exclude the upper mass range selected by the anomaly, especially in cases where the boosted component is generated through dark matter annihilation.

Summary: In this study, anomalies in the measurement of the anomalous magnetic moment of electron (a(e)) and muon (a(mu)) are explained using an Aligned 2-Higgs Doublet Model with right-handed neutrinos. The explanation involves one and two-loop topologies, with a light CP-odd neutral Higgs state (A) contributing significantly to a(mu) and a charged Higgs boson (H-+/-) and heavy neutrinos contributing to a(e). Additionally, a potential signature of this new physics model in the form of H-+/- A production followed by Higgs boson decays is predicted, which can be observed at the Large Hadron Collider.

Summary: The FCC-hh hadron collider will provide access to clean final states, with the Zh production channel showing sensitivity to various SMEFT operators. While O-phi q((3)) shows the best sensitivity, binning in Zh rapidity can improve sensitivity to O-phi q((1)). Estimated bounds at FCC-hh are significantly better than those at HL-LHC and future lepton colliders.

Summary: We present a method to simplify the calculation of finite contributions from heavy particles to EFT Wilson coefficients using on-shell methods. We apply this technique to the one-loop calculation of g-2 and H gamma gamma and demonstrate how finite contributions can be obtained from the product of tree-level amplitudes. By exploiting the parity symmetry of these amplitudes, we discover that in certain cases the total contribution adds up to zero, consistent with previous findings. Our method allows for the search of new natural zeros and enables the straightforward determination of non-zero contributions.

Summary: We study the anomaly induced actions in external gravitational background by solving the trace anomaly constraint and observe changes in their structure under dimensional renormalization (DR) and dimensional reduction (DRed) of the field dependencies. We show that operatorial nonlocal modifications of the counterterms are unnecessary to justify a scale anomaly and only ordinary finite subtractions play a critical role. The interplay between two renormalization schemes, based on dimensional regularization (DR) and a cutoff in d = 4, highlights the ambiguities of DR in handling quantum corrections in a curved background.
