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 introduces a semi-analytical framework based on a drift-diffusion equation to efficiently map ultra-high-energy neutrino fluxes to event rates by modeling the "soft volume" of through-going muon tracks, offering a fast alternative to Monte Carlo simulations that successfully fits IceCube data and reconciles KM3NeT observations.
This paper employs effective field theories to calculate QED corrections for the leptonic decay , establishing a factorization theorem that simplifies the treatment of the heavy tau lepton, demonstrates the cancellation of specific power-suppressed terms, and estimates the structure-dependent uncertainty to be approximately 0.5%.
This paper investigates gravitational wave polarization modes in Weyl quadratic gauge theory of gravity, demonstrating that beyond the standard two tensor modes, the theory predicts two additional vector modes arising from Weyl gauge field fluctuations that could be tested against LIGO-Virgo-KAGRA data.
This paper demonstrates that the null-response channel (NRC) of the Taiji space-based gravitational-wave detector can effectively isolate and test the transverse scalar polarization mode predicted by Gravitational Quantum Field Theory (GQFT), offering a robust, waveform-independent method to probe deviations from General Relativity.
This paper presents a unified analytical framework for the non-thermal production of heavy right-handed neutrinos via derivative coupling to an axion-like inflaton during both inflation and preheating, demonstrating that the resulting helicity-asymmetric abundance can successfully generate the observed baryon asymmetry of the universe through leptogenesis.
This paper presents a prospective study demonstrating that a stacking analysis of hard-spectrum AGNs located behind galaxy clusters, using simulated IACT observations, can significantly enhance sensitivity to Axion-Like-Particle dark matter in the neV mass range by revealing distinctive, predictable spectral irregularities caused by ALP-photon conversions in cluster magnetic fields.
This paper demonstrates that new physics signals in high-energy collider data can be inadvertently absorbed into Parton Distribution Functions (PDFs), potentially hiding them from future searches, but shows that both conservative energy cuts and simultaneous PDF-SMEFT fits using the SIMUnet tool can successfully recover these signals.
This paper argues that the concept of primary dimensions, recently revived as an organizing principle for chiral Lagrangians, is fundamentally inconsistent and advocates for using chiral dimensions—which correspond to loop-order counting—as the correct power-counting scheme for effective field theories like the electroweak chiral Lagrangian with a light Higgs.
This paper presents four-loop fixed-order perturbative calculations for the invariant-mass distribution of the highest- jet in +jet production using the Cambridge/Aachen algorithm, demonstrating that this method effectively suppresses large non-global logarithms at fixed order while performing comparably to the algorithm at all orders.
This paper proposes that the ultra-high-energy gamma-ray emission from LHAASO J0341+5258 originates from cosmic rays escaping a past supernova remnant and illuminating nearby molecular clouds, a scenario that successfully explains the observed spectrum from GeV to TeV energies using both numerical simulations and analytical modeling.
