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 study utilizes the PYTHIA8/Angantyr model to demonstrate that non-collective effects can account for charged hadron multiplicities and baryon enhancement in central d-Au collisions at GeV without requiring a thermalized medium, while highlighting the model's underprediction of invariant yields and the absence of high- suppression.
This paper introduces an efficient COBRA-based pipeline for one-loop effective field theory analysis of the redshift-space galaxy bispectrum, demonstrating that it accurately matches simulation data up to and significantly tightens constraints on key cosmological parameters when combined with the power spectrum.
This paper investigates a minimally extended Standard Model with gauged baryon number, demonstrating that a first-order phase transition in this framework can generate detectable gravitational wave signatures for dark matter and mediator masses in the multi-TeV range, thereby offering a complementary probe to direct detection and collider experiments.
This study demonstrates that space-based gravitational wave detectors, specifically the Taiji mission, can constrain the Higgs cubic and quartic self-couplings by inferring parameters of a first-order electroweak phase transition from the stochastic gravitational wave background, even in the presence of instrumental noise, astrophysical foregrounds, and parameter degeneracies.
This paper proposes that a source for chirality can sustain the chiral plasma instability and generate primordial magnetic fields in an electron-positron plasma even below the 80 TeV temperature threshold where standard thermal equilibrium would otherwise suppress such asymmetry, supporting this claim with analytical and numerical predictions for magnetic field helicity.
MadSpace is a modular C++ library with native GPU support that unifies phase-space construction, adaptive and neural importance sampling, and event unweighting into a compute-graph framework, offering seamless integration with machine learning tools via a high-level Python interface.
This review argues that the unquenched theoretical framework, which incorporates coupled-channel effects and hadronic loops, is essential for resolving long-standing discrepancies in charmonium spectroscopy and explaining the emergence of exotic hadronic states that cannot be accounted for by traditional quenched potential models.
This paper demonstrates that future 10 TeV wakefield colliders, including , , and configurations, can achieve high-precision measurements of Higgs boson electroweak couplings despite beam-beam interactions, with a collider offering sensitivity comparable to muon and alternatives.
This paper demonstrates that a supercooled first-order phase transition cannot immediately result in a matter-dominated universe because bubble collisions generate persistent relativistic gradients that create an intermediate equation of state between matter and radiation, with matter domination only emerging later once these high-momentum modes redshift or the field thermalizes.
This paper proposes a novel axion detection method using a haloscope coupled with a quantum Hall system, demonstrating that the absorption of axion-induced radiation by two-dimensional electrons in a GaAs sample generates a detectable power signal with a favorable signal-to-noise ratio.
