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 presents a theoretical analysis demonstrating that finite size and lifetime effects in heavy-ion collisions modify the momentum-space two-point correlation function of baryon density, resulting in an effective scaling exponent that matches the infinite-system value only within a specific, experimentally accessible momentum range.
This paper presents sensitivity studies for detecting a leptophilic Z' boson at the International Linear Collider and the Linear Collider Facility at CERN, utilizing WHIZARD simulations to evaluate signal and background in the di-muon channel and establish expected limits on Z' couplings to Standard Model leptons at center-of-mass energies of 250 GeV and 550 GeV.
Motivated by recent BESIII measurements, this study demonstrates that the resonance, dynamically generated within the chiral unitary approach, plays a crucial role in the reaction and significantly improves the theoretical description of invariant mass distributions compared to previous analyses that neglected it.
This paper compares proton spin entanglement signatures derived from Basis Light-Front Quantization (BLFQ) and a quark-diquark model, revealing that the latter yields significantly stronger tripartite and bipartite entanglement due to larger W-type and Bell-type correlations, while BLFQ results indicate that stronger coupling and smaller quark masses drive the system toward an effective quark-diquark configuration.
This paper proposes and evaluates three anomalous holographic hard wall models with logarithmic and power-law corrections to baryonic operator dimensions, demonstrating that these modifications significantly improve the description of light baryon spectra and yield approximately linear Regge trajectories compared to the original hard wall model.
The paper evaluates the feasibility of achieving ~3% precision in coherent elastic neutrino-nucleus scattering measurements using mono-energetic electron-capture neutrinos and a compact array of lithium-based bolometers, a capability that could resolve the gallium neutrino anomaly by distinguishing between nuclear effects, source activity errors, and short-baseline oscillations.
This paper adapts cluster-algebraic methods from super Yang-Mills theory to derive candidate alphabets for 5- and 6-point QCD processes, successfully recovering known 1-loop and massless 2-loop results while predicting new letters, including nested square roots for massive 6-point kinematics.
This paper investigates the potential of future direct detection experiments to observe MeV-scale freeze-in dark matter in vector portal models (including dark photons and or extensions), demonstrating that low reheating temperatures enable significant parameter space accessibility via nuclear recoils and solar neutrino signals, even for subcomponent dark matter fractions.
This paper employs a purification scheme to analyze the Krylov complexity of thermal states across the early universe's inflationary, radiation-dominated, and matter-dominated eras, revealing an exponential growth of complexity and strong dissipation during inflation that transitions to saturation and weak dissipation in later epochs due to particle production.
This study utilizes the Interacting Boson Model-2 (IBM-2) to successfully investigate the rare intruder nuclear levels in , , and , attributing their anomalous positions to double subshell closures and demonstrating strong agreement between theoretical predictions and experimental data for various transition rates.
