A Vector-Like Lepton Interpretation of the High-Energy Nuclear Recoil Candidate in LUX-ZEPLIN

This paper proposes that a high-energy nuclear recoil candidate observed by the LUX-ZEPLIN experiment can be explained by singlet-doublet Majorana dark matter undergoing spin-dependent scattering via a ZZ boson, a scenario that simultaneously satisfies thermal relic constraints, evades low-energy background limits through a Higgs blind spot, and remains testable via solar neutrino searches.

Final-state effects on the transverse-momentum spectra of charged hadrons in p+Pbp+Pb and Pb+PbPb+Pb collisions at sNN = 5.02\sqrt {s_{\rm{NN}}}~=~5.02~TeV using the modified Tsallis distribution

This study utilizes a modified Tsallis distribution to successfully model ATLAS data on charged-hadron transverse-momentum spectra in p+Pbp+Pb and Pb+PbPb+Pb collisions at 5.02 TeV, revealing distinct centrality-dependent trends in collective flow and parton energy loss that quantify the interplay between these medium effects.

Endothermic dark matter with a light dark photon and the LUX--ZEPLIN high-energy nuclear-recoil candidate

This paper proposes that the single high-energy nuclear-recoil candidate observed by the LUX-ZEPLIN experiment can be explained by endothermic inelastic dark matter with TeV-scale masses and a GeV-scale dark photon, a model that successfully reproduces the observed relic abundance while satisfying cosmological constraints and remaining testable in future accelerator searches.

Small-Scale Clustering of Primordial Black Holes: The Little Red Dot Mass Function and the High-Redshift Galaxy Tension

This paper proposes that supermassive black holes in JWST-discovered "little red dots" originate from runaway mergers of primordial black holes within small-scale clusters, a mechanism that simultaneously explains their observed mass and compactness while alleviating tensions with high-redshift galaxy formation in Λ\LambdaCDM cosmology.

Complex Scalar Dark Matter with a Vector-Like Quark and Lepton: Precision, Flavor, and HL-LHC

This paper investigates a minimal extension of the Standard Model featuring a complex scalar dark matter candidate stabilized by a Z3\mathbb{Z}_3 symmetry alongside vector-like quarks and leptons, performing a comprehensive analysis of flavor, precision, and collider constraints to identify viable TeV-scale parameter regions and demonstrate the complementarity of multi-messenger searches in probing this framework.

Three Predictions for Partonic Energy Loss from Light to Heavy Ion Collisions

This paper presents three predictions for partonic energy loss in ultrarelativistic light ion collisions by combining BDMPS-Z, weighted path, and JEWEL models with realistic 16^{16}O and 20^{20}Ne geometries to demonstrate how ion size characteristically influences energy loss in small quark-gluon plasma systems.

Naturally small Dirac neutrino mass and B−LB-L dark matter

This paper proposes a gauged B−LB-L extension of the Standard Model where the singlet scalar carries a B−LB-L charge of 3 or 4 to naturally generate small Dirac neutrino masses, simultaneously providing a viable dark matter candidate and predicting observable stochastic gravitational waves and deviations in the effective number of relativistic degrees of freedom.

Dark matter glueball candidate from a G(2)G(2)--E6E_6--E7E_7 exceptional grand unified theory: GG-parity, spin, mass and stability

This paper investigates the stability and properties of a dark matter glueball candidate within a G(2)G(2)–E6E_6–E7E_7 grand unified theory, concluding that while a 1+−1^{+-} state is favored at low energies, the minimal embedding lacks an exact ultraviolet dark GG-parity due to chiral obstructions that conjugate color, though a modified Higgs sector can remove scalar barriers while leaving the fundamental UV instability unresolved.
