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 the scattering of doubly charmed baryons with light pseudoscalar mesons using chiral effective theory up to next-to-leading order, where unknown parameters are constrained by recent lattice data to predict resonance, virtual, and bound states as well as scattering observables at physical quark masses.
This paper applies quantum estimation theory, specifically the quantum Fisher information matrix and quantum fidelity, to demonstrate that parameter degeneracies in three-flavor neutrino oscillation probabilities do not necessarily imply indistinguishable quantum states, thereby revealing hidden quantum-information differences between degenerate solutions.
This paper presents a method to overcome the numerical evaluation challenges of canonical differential equations for Feynman integrals on arbitrary geometries by solving auxiliary rational differential equations, a strategy implemented in a C++ package and applied to two-loop master integrals in di-jet and +jet hadro-production.
This paper interprets nine statistically significant LHC decay channels around 650 GeV as evidence for a sequence of Beyond-the-Standard-Model resonances, specifically a spin-2 Kaluza-Klein graviton (T700) and a wide scalar (H650), which align with Randall-Sundrum and composite model predictions and offer promising targets for future electron-positron colliders.
This paper proposes an alternative test statistic to the standard likelihood ratio test that allows particle physicists to focus statistical power on specific, physics-motivated regions of the parameter space, demonstrating improved performance in Higgs and dark matter searches while utilizing machine learning to efficiently calibrate critical values for valid confidence intervals.
This paper demonstrates that within a specific kinematic recoil framework and hadron mass scheme, the complex resummation required to calculate anomalous dimensions for non-perturbative power corrections in hadronic observables reduces to a simple exponential form, even beyond the two-jet limit.
This paper investigates a minimal extension of the Standard Model with Dirac dark matter annihilating via a boson, deriving stringent constraints on its parameters by comparing predicted high-energy neutrino fluxes with observational data, incorporating freeze-in relic abundance limits, and considering gravitational wave signatures from cosmic strings.
This paper reports experimental evidence of power-law late-time decay in two fluorescent compounds, demonstrating that while the decay lifetime is universal, the specific late-time deviations depend on the detection channel, consistent with a divergent spectral density model in multichannel quantum mechanics.
The Hadrosymmetric Twin Higgs model offers a unified solution to both the little hierarchy problem in particle physics and current cosmological tensions by partially reducing the Hubble constant discrepancy to and alleviating the anomaly without violating constraints on relativistic species.
This paper demonstrates that the transverse momentum spectra of charged particles in proton-proton collisions can be robustly decomposed into distinct soft and hard components that remain invariant across multiplicity classes, supporting a two-component interpretation as a viable alternative to hydrodynamical models.
