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 reviews Higgs inflation with a non-minimal coupling to gravity, demonstrating that such a coupling can flatten the Higgs potential sufficiently to render the electroweak vacuum metastable yet viable for inflation, even when the Standard Model alone predicts a deeper, unstable minimum at high energies.
This paper presents NLO QCD corrections for four-top quark production and decay in the channel at the LHC, utilizing the narrow-width approximation to preserve spin correlations while analyzing the sensitivity of results to kinematic cuts on light jets.
This proceeding reviews the concept of "magic" in quantum computing and demonstrates that top quark pair production at the Large Hadron Collider naturally generates this resource, offering a novel high-energy physics platform for studying quantum computational advantage.
This paper presents an updated global SMEFT fit using LHC Run II data and precise electroweak precision observables, while also evaluating the future constraints on SMEFT parameters achievable at the HL-LHC and proposed high-energy colliders (FCC-ee and CEPC).
This paper presents recent progress in calculating complete next-to-leading order (NLO) corrections for associated top-quark pair production with one or two isolated photons, specifically focusing on the simultaneous inclusion of higher-order effects and photon radiation in both production and decay processes to quantify their impact on realistic final states.
This paper presents three recent ATLAS analyses using Run-2 data to systematically explore deviations from the Standard Model in the top quark sector via the Standard Model Effective Field Theory (SMEFT), demonstrating how combined measurements enhance sensitivity to Wilson coefficients and tighten constraints on new physics.
This paper proposes and extends a Direct Diffusion network framework that efficiently encodes computationally expensive off-shell effects in top pair production by transforming approximate events into full off-shell results, aiming to meet the precision requirements of upcoming LHC runs while incorporating higher-order effects.
This paper presents a comprehensive CMS analysis that combines top quark, Higgs boson, electroweak, and QCD measurements, along with LEP and SLC data, to constrain 64 Wilson coefficients both individually and through a simultaneous fit to 42 linear combinations within an Effective Field Theory framework.
This paper introduces a chiral-rotation-invariant framework that accounts for mixing with heavy pseudoscalar resonances to correct the misdescribed production and decay of GeV-scale axion-like particles, revealing that existing experimental bounds and projected sensitivities can shift by up to an order of magnitude.
This paper proposes an extension of the simplified template cross-section (STXS) framework for production by incorporating -sensitive observables, specifically the Collins-Soper angle, to significantly improve the sensitivity to violation in the top-Higgs Yukawa coupling at both 300 and 3000 fb integrated luminosities.
