This study investigates the magnetic moments of strange hidden-bottom pentaquark states within the constituent quark model across molecular and compact configurations, finding that their electromagnetic properties are primarily governed by global spin–flavor correlations and light–strange quark dynamics rather than specific internal clustering details due to heavy-quark mass suppression.
This paper investigates how spatial temperature gradients in heavy-ion collisions induce anisotropic, long-range correlations along isotherms via singular eigen-modes, suggesting that azimuthally sensitive observables could provide a novel avenue for detecting QCD phase transition signals.
This paper demonstrates that while relaxing the assumption of equal on-shell and off-shell Higgs coupling modifiers in Standard Model extensions can allow for a larger total width, realistic constraints still limit this increase to at most a factor of two compared to the standard indirect bounds.
This thesis establishes a rigorous, algorithmic framework for restoring gauge and BRST invariance in chiral gauge theories using the BMHV scheme with non-anticommuting , successfully demonstrating its feasibility through the complete 4-loop renormalisation of an Abelian theory and the 1-loop renormalisation of the full Standard Model.
This paper demonstrates the feasibility of utilizing decay electrons and positrons from future muon colliders (IMCC and TRISTAN) as high-energy, high-repetition-rate beams for new light-particle searches, proposing complementary strategies to probe dark matter and axion-like particles beyond the reach of current experiments.
This paper argues that the Flavor Democracy hypothesis can be revived by introducing Vector-Like Leptons and Quarks to resolve the top quark mass anomaly, while emphasizing the urgent need to move beyond current restricted experimental models to a comprehensive re-evaluation that accounts for all viable decay channels.
This paper demonstrates that TeV-scale heavy neutral leptons in an inverse-seesaw model can simultaneously generate neutrino masses and produce light pseudo-Nambu-Goldstone boson dark matter via freeze-in, establishing a predictive link between neutrino mass generation, dark matter abundance, and decay signatures testable at future colliders and neutrino detectors.
This paper presents a combined analytical and numerical study of field theory cosmic strings, demonstrating that while translational Goldstone modes lack nontrivial curvature corrections, massive shape modes couple to worldsheet curvature to induce parametric instabilities that transfer energy between sectors.
This paper derives one-loop quark contributions to effective vertices coupling magnetic fields and the condensate within a magnetized quark-gluon plasma, identifying specific effects that could signal QGP creation in heavy ion collision experiments.
This paper identifies fluorine-based compounds, particularly octafluoropropane, as optimal targets for measuring subleading axial-vector contributions in coherent elastic neutrino-nucleus scattering, demonstrating that such experiments could determine the axial coupling at the level and probe spin-dependent new physics.
This paper investigates eV-scale sterile neutrino mixing schemes (3+1, 1+3, and 2+2) in light of short-baseline anomalies and global fit data, finding the 3+1 model most viable and constraining the sterile neutrino mass to approximately 4.7 eV for both normal and inverted hierarchies through neutrinoless double beta decay analysis.
Using a coupled-channels framework derived from a constituent quark model, this study predicts a rich spectrum of resonant and virtual tetraquark candidates exhibiting heavy-quark spin symmetry multiplets, with specific guidance provided for their experimental detection through characteristic decay patterns and widths.
This paper applies the Principle of Maximum Conformality to the next-to-next-to-leading-order perturbative QCD calculation of the rare Higgs decay , successfully eliminating renormalization and factorization scale ambiguities to provide a robust, scale-invariant prediction for the decay width that offers a precise probe for the charm-quark Yukawa coupling.
This paper presents a novel numerical integrator for evaluating Feynman master integrals by treating branch cuts differently, achieving significantly faster computation times in double and quadruple precision that enable efficient on-the-fly calculations in Monte Carlo generators and the generation of grids for complex topologies.
This paper establishes the current best constraints on the charge and mass of fermionic and bosonic millicharged particles by analyzing their Schwinger mechanism production in thunderstorms across Solar system planets, with the most stringent limits derived from Saturn's atmospheric observations.
This paper analyzes an inverse seesaw model with non-degenerate pseudo-Dirac heavy states governed by specific discrete flavor symmetries, finding that while current charged lepton flavor violation limits do not strongly constrain the parameter space compatible with observed lepton mixing, upcoming experiments like Mu3E, COMET, and Mu2e are expected to provide significant tests.
This paper presents a unified Froggatt-Nielsen effective theory with three right-handed neutrinos and complex coefficients that simultaneously explains fermion flavor hierarchies, neutrino masses, dark matter, and the baryon asymmetry of the Universe, demonstrating that successful thermal leptogenesis is viable in both freeze-in and freeze-out scenarios.
This paper demonstrates that for near-horizontal cosmic-ray air showers, the longitudinal development can be reconstructed by mapping the time dependence of the observed induced electric field to atmospheric slant depth, enabling the inference of key shower parameters such as from single observer measurements.
This paper presents a method for accelerating the numerical evaluation of Feynman integrals in the Minkowski regime by rewriting them as sums of real, positive integrands multiplied by complex prefactors to avoid contour deformation, achieving performance gains of several orders of magnitude compared to traditional techniques.
This paper presents a likelihood-based comparison of locally constructed empirical and theoretically-motivated gamma-ray background models, finding that empirical descriptions provide statistically competitive fits to data on degree scales in high-latitude regions relevant for indirect dark matter searches.
