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.
At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper establishes new constraints on the mixing angle of light CP-even scalars with the Standard Model Higgs boson by analyzing non-detections of gamma-ray excess from SN1987A in historical Solar Maximum Mission satellite data, which would have resulted from scalars produced via nucleon bremsstrahlung and subsequently decaying into photons.
This paper proposes that quantum sensors can detect bursts of ultralight bosonic fields emitted during violent astrophysical events, thereby establishing a new multimessenger astronomy channel that remains viable even when accounting for matter screening effects.
This semi-historical article provides a basic presentation of quantum field theory's mathematical formalism and its essential features, such as particle creation and destruction, to readers familiar with classical and non-relativistic quantum mechanics while also aiming to engage interested non-physicists.
This paper proposes a novel mechanism for generating high-frequency gravitational waves at approximately Hz through gravitational transition radiation, where particles emit gravitons as their masses change while traversing expanding bubble walls during first-order phase transitions in the early Universe.
This study utilizes PYTHIA 8 and EPOS-LHC models to demonstrate that particle-identified balance functions in 13 TeV proton-proton collisions exhibit distinct dependencies on event multiplicity and spherocity, revealing that while PYTHIA 8 reflects fragmentation-dominated dynamics, EPOS-LHC captures collective effects like radial flow and diffusion that mimic heavy-ion behavior, thereby offering a powerful tool to disentangle hadronization mechanisms and medium-like collectivity in small collision systems.
This paper demonstrates that the Witten-O'Raifeartaigh potential can support a unified cosmological model where Warm Inflation occurs on its steep left wing and transient dark energy arises on its flatter right wing, provided the potential is normalized differently for each era and the quintessence field incorporates dissipative dynamics to sustain slow-roll.
This paper explores extending Bimetric MOND (BIMOND) to create variable- theories that naturally satisfy local constraints on the constancy of Newton's constant while allowing for a different, enhanced effective gravitational constant () in cosmological settings to potentially explain dark matter effects without new degrees of freedom.
This paper derives a model-independent upper limit on the amplitude of a chiral gravitational wave background produced before the electroweak epoch, which, for high reheating temperatures, provides a significantly more stringent constraint than standard big bang nucleosynthesis bounds at frequencies above the MHz scale.
This paper calculates the ground-state energy levels and hyperfine structure of three- and four-particle lepton bound states in quantum electrodynamics using a variational method with Gaussian basis functions that accounts for pairwise spin-spin interactions.
This paper introduces VarP-GP, a cost-efficient Bayesian emulator that leverages variable statistical precision in Monte Carlo simulations to significantly reduce uncertainty in quark-gluon plasma modeling, thereby enabling previously infeasible multi-model calibrations of high-energy nuclear collision data.
