Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

This paper investigates IceCube DeepCore's capability to detect Non-Standard neutrino Interactions using a model-independent parameterization and evaluates its potential to resolve the tension between T2K and NOvA measurements of the CP-violating phase .
This paper demonstrates that coupling an inflaton to the D-term sectors of chiral superfields, rather than using conventional Yukawa couplings, can enhance the amplitude of stochastic gravitational waves generated during reheating by at least an order of magnitude, thereby highlighting the potential for observing supersymmetric imprints in the gravitational-wave background.
This paper proposes that the resonance is an -wave -- molecular state and supports this hypothesis by calculating its strong decay widths, which reveal a dominant channel and distinctive patterns in multi-pion transitions that serve as experimental signatures for heavy-quark symmetry.
This study demonstrates that the eigen-microstate approach (EMA) serves as a robust, background-independent method for identifying critical fluctuations in relativistic heavy-ion collisions by effectively filtering non-critical correlations and capturing the fractal nature of criticality through characteristic eigenvalue patterns and finite-size scaling behaviors.
Using a non-relativistic potential quark model, this study calculates the inclusive weak decay width of charmed baryons to be approximately GeV, demonstrating that this process, with a signal significantly exceeding background contributions, offers a viable discovery channel for the doubly heavy baryon at the LHC.
This paper establishes a unified theoretical framework for spin-1 particles by discussing spin density matrix bases, introducing equilibrium distributions, and formulating perfect spin hydrodynamics that parallels the existing description for spin-1/2 particles.
This paper investigates the cosmological dynamics of a two-axion quintessence model, demonstrating that multiple axions—particularly with cross-interactions—can generate novel dark energy equation of state behaviors and relax the requirement for super-Planckian decay constants, thereby offering alternative explanations for DESI observations that deviate from standard single-field thawing quintessence.
This study presents an extensive nonperturbative analysis of vacuum polarization and pair production in time-dependent electric fields using a revised quantum kinetic equation framework, computing key observable quantities and demonstrating consistency with the Dirac-Heisenberg-Wigner formalism to establish a firmer theoretical basis for strong-field physics.
This paper investigates the photoproduction of the exotic charged states and off nuclei using a collision model based on the nuclear spectral function, demonstrating that absolute and relative observables calculated for various internal structure scenarios (compact tetraquarks, molecules, and mixtures) are sensitive enough to distinguish their nature in future high-luminosity electron-ion collider experiments.
This review introduces the fundamental concepts of group theory and gauge symmetry to construct and quantize gauge-invariant Lagrangians, while also exploring modern on-shell amplitude methods and presenting the Standard Model through its specific symmetry structures and matter content.
