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 proposes a string-derived supergravity model combining the Standard Model with gauged and modular symmetry, where anomaly cancellation conditions uniquely determine flavor structures and axion properties, predicting a specific axion mass and coupling while suppressing flavor-violating interactions and reproducing observed neutrino data.
This paper demonstrates that renormalization group running of the PMNS matrix, enhanced by light neutrinophilic new particles in low-scale neutrino mass models, can significantly increase the rate of high-energy "double bang" events at IceCube, making these signatures comparable to standard model predictions and offering a potential window into the origin of neutrino mass.
This paper demonstrates that future subpercent-level precision measurements of the Standard Model Higgs diphoton signal strength can indirectly probe and decisively constrain the parameter space of Type-II Seesaw models that currently evades direct LHC searches due to cascade decays.
Using the deep-learning algorithm DINGO-lensing to overcome computational limitations, this study reanalyzes the gravitational wave candidate GW231123 with over 200,000 simulations and concludes that it is not a lensed event due to its statistical significance falling below 4, while highlighting the critical impact of waveform systematics and the potential for future discoveries with improved detection statistics.
This paper investigates the two-body nonleptonic decays of into accompanied by pseudoscalar or vector mesons using the naive factorization approach, calculating decay amplitudes across various topologies to determine rates and branching ratios for comparison with other theoretical predictions and experimental data.
This paper demonstrates that the energy levels of QED bound states, such as muonic hydrogen, can be calculated using matrix elements of the energy-momentum tensor trace, showing analytically and diagrammatically how this method yields results consistent with standard one-loop Lamb shift calculations despite employing different diagrammatic sets.
This paper presents an updated analysis of the decay angular distribution incorporating transverse beam polarization, confirming a slope parameter while identifying small but non-negligible two-photon interference effects and predicting a significant azimuthal modulation that motivates future two-dimensional angular studies.
This paper validates a modified Teukolsky framework for predicting gravitational-wave ringdown spectra in effective field theories by successfully passing two rigorous null tests and confirming consistency between two independent numerical methods, thereby establishing its reliability for future strong-field tests of General Relativity.
This study demonstrates that while Monte Carlo neutrino transport in neutron star mergers confirms thermalization in hot, dense regions, significant non-equilibrium deviations in moderately warm zones reveal that energy-averaged agreement with thermal assumptions is insufficient for accurately predicting weak interaction rates and composition evolution.
This paper demonstrates that incorporating Urca processes involving parity partners of nucleons and hyperons within a parity doublet model significantly improves the agreement between neutron star cooling simulations and observed surface temperatures and ages.
