This paper evaluates the viability of a light inflaton scenario with a quartic potential by integrating recent Atacama Cosmology Telescope constraints with bounds from various collider and intensity-frontier experiments, while also exploring its implications for dark matter production during reheating.
This paper presents a light-front Faddeev description of baryons in two-dimensional QCD with that successfully reproduces the chiral spectrum, isospin, and strangeness properties across weak and strong coupling regimes, including the first valence-level calculation of hyperon spectroscopy which reveals an inverted - ordering and validates key mass relations like Gell-Mann–Okubo and Coleman–Glashow.
This paper presents the first simultaneous Color Glass Condensate fit to HERA deep inelastic scattering and RHIC/LHC forward hadron production data using LO BK evolution with running coupling, demonstrating that a global fit with collider-specific K-factors achieves excellent agreement with data while revealing complementary constraints on dipole evolution and identifying fragmentation functions and factorization scales as dominant systematic uncertainties.
This paper investigates the impact of a novel flavor-mixing interaction arising from vacuum polarization on the parton distribution functions of charged kaons and pions within the U(3) Nambu--Jona-Lasinio model, demonstrating that these mixing effects, which are proportional to quark effective mass differences, significantly improve the agreement of theoretical predictions with experimental data at specific momentum fractions.
This paper proposes a method using neural control variates, specifically a signed control variate constructed from two normalizing flows, to minimize event weight ranges, eliminate negative weights, and significantly reduce the computational cost of both LO and NLO predictions through enhanced phase-space integration and event generation.
This paper demonstrates that including a dimension-six operator in the Higgs potential significantly extends the lifetime of oscillons in the Standard Model's bosonic sector for physical mass ratios and couplings within current experimental bounds.
This paper applies the Supersymmetric Quantum Mechanics factorization method to the Cornell potential to calculate the mass, binding energy, hyperfine splitting, decay widths, and spatial characteristics of the toponium system, identifying the di-gluonic decay mode as dominant and determining state masses of approximately 344.1 GeV.
This paper demonstrates that combining axion-induced interactions within the Polyakov-Nambu-Jona-Lasinio model and four-dimensional Einstein-Gauss-Bonnet gravity stiffens the quark matter equation of state, resulting in quark stars with higher maximum masses, larger radii, and reduced compactness that better align with current observational constraints than standard general relativity models.
This thesis reviews recent advances in sphaleron rate calculations for electroweak baryogenesis, provides pedagogical introductions to related topological field configurations, and discusses the broader implications of first-order phase transitions for collider searches and primordial black hole formation.
This paper utilizes a nonperturbative light-front Hamiltonian framework to demonstrate that the von Neumann entanglement entropy of quark-antiquark pairs in heavy quarkonium serves as a novel probe of nonperturbative structure, directly linking quantum information measures to transverse momentum dependent parton distributions and revealing significant sensitivity to meson polarization.
