Gravitational D-form factors of the nucleon and pion with mixing between two-quark and four-quark states

This paper investigates the gravitational $D$ -form factors of the nucleon and pion within an extended linear sigma model incorporating two- and four-quark mixing, finding that while this mixing suppresses the nucleon $D$ -form factor to match lattice-QCD results (mimicking effects of chiral invariant mass), it uniquely modifies the pion's momentum-transfer dependence, thereby suggesting that a combined analysis of both form factors is necessary to distinguish between these distinct physical mechanisms.

Probing an up-phobic Higgs at colliders: the role of $b$ -associated production in the democratic 3HDM

This paper demonstrates that in the up-phobic limit of the democratic three Higgs-doublet model, $b$ -associated production becomes the dominant heavy-Higgs mechanism, making existing and future LHC searches in this channel the most sensitive probes for constraining the model's parameter space.

Mechanisms of $D \bar{D}$ pair production in $e^{+} e^{-} \to e^{+} e^{-} D \bar{D}$ and $AA \to AA D \bar{D}$ reactions and production of exotic charmonia

This paper analyzes mechanisms of $D\bar{D}$ pair production in $e^+e^-$ and ultraperipheral heavy-ion collisions, concluding that the observed $D^0\bar{D}^0$ continuum bump originates from $t/u$ -channel exchanges rather than a resonance, while also characterizing the $\chi_{c2}(3930)$ as a candidate for the $\chi_{c2}(2P)$ state and providing branching fraction estimates and differential distributions for Belle II and LHC kinematics.

Radiative corrections to the subprocess of annihilation of quark-antiquark pair of prompt photon production in proton-proton collisions at NICA energies $\sqrt{\mathbf{s}}$ = 10 GeV

This paper presents a comprehensive theoretical and numerical study of QCD and QED radiative corrections to prompt photon production via quark-antiquark annihilation in proton-proton collisions at NICA energies ( $\sqrt{s}=10$ GeV), utilizing FeynCalc and PYTHIA 8.316 to analyze differential cross-sections and spin asymmetries, revealing that these corrections are significant at low energies and small transverse momenta with excellent agreement between analytical calculations and simulations.

Spin relaxation of heavy quarks from momentum diffusion in the quark-gluon plasma

This paper develops a stochastic framework linking heavy-quark spin relaxation in the quark-gluon plasma to momentum diffusion via Thomas precession, deriving a direct relation between the spin-relaxation time and the momentum-diffusion coefficient $\kappa$ and providing quantitative estimates for charm and bottom quarks based on recent theoretical and phenomenological inputs.

Generalized fluctuation-dissipation theorem and Einstein relation in rotating equilibrium

This paper derives a generalized fluctuation-dissipation theorem and a model-independent Einstein relation for vector fields in rotating thermal equilibrium, revealing rotation-induced tensorial corrections and a new mechanism for heavy quarkonium orbital polarization linked to spectral zero modes.

Near Threshold Kaluza-Klein Graviton Decays and the Dark Dimension

This paper demonstrates that near-threshold intra-tower decays of Kaluza-Klein gravitons follow a $d$ -wave ( $p^5$ ) scaling rather than the previously assumed $s$ -wave ( $p$ ) behavior, which effectively rules out these gravitons as dark matter in a flat dark dimension and necessitates a significantly smaller extra-dimensional radius to satisfy cosmological constraints on gamma-ray backgrounds and reheating temperatures.

Effective field theory of scalar glueballs: Form factors and interaction radii

This paper develops a gauge-invariant effective field theory for scalar glueballs based on the Yang-Mills gluon condensate, deriving a parameter-free interaction radius and form factor for the $f_0(1710)$ resonance that show excellent agreement with first-principles lattice Yang-Mills calculations.

Trace-anomaly decomposition and universal dark matter scaling in compact stars

This paper demonstrates that dark matter admixture in neutron stars induces a smooth, universal scaling in the trace anomaly and stellar structure governed by a mass-loading parameter, providing a distinct diagnostic to differentiate these effects from the sharp discontinuities caused by first-order hadron-quark deconfinement while revealing that even small dark matter fractions can tension the existence of $2\,M_\odot$ neutron stars.

Electron and monopole properties in a dark matter model

This paper generalizes Electroweak theory by incorporating a dark sector with massive photons and monopoles to analyze how mixing interactions transform leptons into dyons and determine the experimental observability of monopoles, particularly depending on the dark photon's mass.
