COSMOS: A numerical relativity code specialized for PBH formation
COSMOS is a standalone, OpenMP-parallelized C++ numerical relativity code designed to simulate primordial black hole formation by solving the Einstein equations in 3+1 dimensions using specialized non-Cartesian scale-up coordinates and fixed mesh refinement to handle non-linear gravitational dynamics.
Interpreting Light Scalar Excesses and Heavy Scalar Cascades in the -Term Extended NMSSM
This paper demonstrates that the -term extended NMSSM can simultaneously accommodate persistent scalar excesses at LEP and the LHC while satisfying stringent heavy scalar cascade constraints, offering viable parameter regions with distinct coupling patterns and predicting specific long-lived neutralino signatures for positive- scenarios.
Azimuthal decorrelation in diffractive dijet production
This paper calculates the azimuthal angular decorrelation of diffractive dijets in ultra-peripheral heavy-ion, $ep$, and $eA$ collisions using all-order resummation of soft gluon emissions to demonstrate that this observable serves as a promising probe for non-perturbative diffractive transverse momentum-dependent distributions, with numerical predictions provided for LHC, HERA, and the future EIC.
Cumulant dynamics in finite-memory diffusion
This paper extends the standard Fickian diffusion model to Maxwell–Cattaneo diffusion to account for finite current-relaxation time, deriving closed evolution equations that reveal how this memory effect suppresses, shifts, and reshapes the non-monotonic behavior of conserved charge cumulants in the quark-gluon plasma.
Comment on "QCD-factorization amplitudes from flavour symmetries: beyond the $SU(3)$ symmetric case''
This Comment refutes the assertion that Electroweak Penguin-Tree relations (ETRs) are invalid by demonstrating that they are mathematically rigorous group-theoretical results, thereby explaining the discrepancy between the authors' poor fit using ETRs and a recent study's successful fit that discarded them.
New Windows on Heavy Dark Matter: Mineral Melt Modelling and X-Ray Readout for Muscovite Mica
This paper proposes a novel framework for detecting heavy composite dark matter using muscovite mica as a paleodetector, combining Sedov-Taylor thermal spike modeling and SRIM/TRIM simulations with a new rapid X-ray fluorescence readout method to establish projected sensitivities and critique previous exclusion limits.
Strong Constraints on Dark Photon and Scalar Dark Matter Decay from INTEGRAL and AMS-02 data
This paper utilizes INTEGRAL and AMS-02 data to establish stringent lower limits on the decay lifetimes of bosonic dark matter (specifically dark photons and scalar models) ranging from 1 MeV to 2 TeV, reaching up to seconds for masses above 10 GeV.
Leptogenesis and Neutrino Masses Via Pseudo-Dirac Gauginos
This paper proposes a -symmetric supersymmetric model where pseudo-Dirac bino and wino gauginos generate light neutrino masses via a hybrid inverse seesaw mechanism and simultaneously produce the observed baryon asymmetry through $CP$-violating bino oscillations and decays, requiring a decoupled spectrum with TeV-scale binos, multi-TeV sfermions, and a high messenger scale that yields distinctive displaced vertex signals at the LHC.
Evolving Dark Sector and the Dark Dimension Scenario
This paper proposes a string theory-inspired model where an evolving dark dimension links varying dark energy and dark matter masses through a scalar field, successfully fitting recent DESI and supernova data while naturally explaining apparent phantom behavior and satisfying Swampland and fifth-force constraints.
