Analysis of $J/ψ$ and $ψ(2S)$ Charmonium Production in Ultraperipheral Lead-Lead and Proton-Lead Collisions at LHC Energies

This study utilizes the STARlight program and a two-gluon exchange model to analyze charmonium production in ultraperipheral PbPb and pPb collisions at LHC energies, introducing a phenomenological suppression factor to successfully reconcile theoretical predictions with experimental rapidity and transverse momentum distributions in PbPb collisions while confirming the model's validity for future UPC studies.

EGUP effects on the thermodynamic properties of the Kerr-Newman black hole surrounded by quintessence

This paper investigates how the Extended Generalized Uncertainty Principle (EGUP) influences the thermodynamic properties, stability, and remnant characteristics of a Kerr-Newman black hole surrounded by quintessence, while comparing these effects with those derived from the Generalized Uncertainty Principle (GUP) and the Extended Uncertainty Principle (EUP) to illustrate variations across different cosmic eras.

SN1987A Constraints of Light $\boldsymbol{Z'}$ with Non-Mixing Polarisations

This paper revises SN1987A constraints on light gauge bosons, such as those in the $L_\mu-L_\tau$ model, by demonstrating that suppressed polarisation intermixing in the low-coupling regime necessitates treating longitudinal and transverse modes as independent energy transporters, thereby significantly altering the resulting bounds on the parameter space.

Scalar diquarks in the QCD vacuum

This study employs the dynamical hadronization technique within the functional renormalization group approach to two-flavor QCD to derive low-energy constants for the pion, $\sigma$ -meson, and scalar diquark from first principles, thereby providing microscopic constraints for models of dense quark matter and color superconductivity.

Nuclei in high-energy neutrino sources: A multimessenger study of in-source propagation

This paper utilizes Monte Carlo simulations of nuclear and electromagnetic cascades in the NGC 1068 source to demonstrate how joint gamma-ray and neutrino observations, including a re-analysis of archival COMPTEL data, can constrain the nuclear composition and physical conditions of high-energy astrophysical environments.

Primordial Black Holes: A Review of Formation and Evolution

This review synthesizes the hydrodynamic, relativistic, and quantum mechanisms governing Primordial Black Hole formation and evolution, challenging standard Hawking evaporation models by proposing Planck-scale relics and highlighting the potential for next-generation gravitational wave observatories to provide definitive evidence for their existence as dark matter candidates.

Event isotropy in perturbative QCD

This paper presents the first theoretical study of event isotropy in perturbative QCD, providing semi-analytic and numerical calculations at leading and next-to-leading orders, as well as all-order resummed predictions matched to fixed-order results to achieve NLL+NLO accuracy.

Mapping jet substructure in heavy-ion collisions with track functions

This paper investigates how track functions, which encode the flow of energy from partons to charged hadrons, are modified by the quark-gluon plasma in heavy-ion collisions, demonstrating that their non-linear evolution and higher moments can discriminate between different jet quenching models and provide a direct test of quantum field theory predictions within the medium.

Neutrinoless double $\beta$ decay and leptogenesis in seesaw model

This paper argues that the right-handed neutrino field in the Type I seesaw model is not a Majorana fermion, thereby precluding neutrinoless double beta decay, and proposes that both leptogenesis and neutrinoless double beta decay can be realized by redefining the model with C-symmetric Majorana fermions via a Bogoliubov transformation.
