This paper calculates the shear viscosity of quantum chromodynamics across finite baryon, strangeness, and charge densities by combining perturbative QCD results at high densities with an excluded-volume hadron resonance gas model at low densities, while also presenting next-to-leading order weak-coupling results and analyzing the convergence of the perturbative series.
This review article discusses how the LISA Cosmology Working Group's analysis demonstrates that while strong parameter degeneracies complicate model reconstruction, gravitational wave signals from first-order phase transitions can still provide complementary constraints on Beyond-Standard-Model scenarios alongside particle collider data.
This paper introduces a robust, jet-free method for measuring energy-energy correlators in LHC proton-proton collisions using event topology and a leading charged hadron reference, which successfully extends measurements to low transverse momentum regimes and reveals distinct QCD dynamics, including the dead-cone effect in heavy flavor events.
This paper proposes a unified framework based on modular symmetry and a type-III seesaw mechanism, where a single complex modulus simultaneously explains neutrino masses, generates the baryon asymmetry via resonant leptogenesis, and produces asymmetric dark matter with a predicted mass of 0.1–2 GeV, all while remaining consistent with current neutrino oscillation data and future experimental constraints.
This study utilizes PYTHIA8 to analyze charge balance functions of identified hadrons in high-multiplicity jets at TeV, revealing a narrowing balancing width and species-dependent dynamics that suggest multiparton interactions and color reconnection can generate collective-like features within small systems.
This paper conducts a comparative analysis of Gaussian Process emulators to identify the most effective method for minimizing uncertainty in Bayesian parameter extraction for 3+1D relativistic heavy-ion collisions, thereby improving the interpretation of experimental data regarding the Quark Gluon Plasma.
This study employs Bayesian inference with high-accuracy model emulators to analyze RHIC Beam Energy Scan data, thereby providing robust constraints on Quark-Gluon Plasma transport properties, elucidating the sensitivity of experimental observables to model parameters, and generating predictions for -differential observables with estimated systematic uncertainties.
This paper presents a Gaussian Process generative model that integrates theoretical constraints from lattice QCD and hadron resonance gas to produce diverse, smooth crossover equations of state for nuclear matter, thereby establishing a foundation for future Bayesian inference studies using relativistic heavy-ion collision data.
This paper utilizes an open quantum system formalism to calculate the inflaton four-point correlation function in axion inflation, demonstrating that the derived parity-odd expansion coefficients in the large limit not only confirm parity violation but also align with recent observational data from galaxy surveys.
This paper investigates the phenomenological implications of a Left-Right Symmetric Model extended with a double type-I seesaw mechanism, demonstrating how fully determined Dirac mass textures can enhance right-handed neutrino contributions to neutrinoless double beta decay and the charged lepton flavor violation process within parameter spaces accessible to current and future experiments.
