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 and evaluates a search strategy for heavy exotic leptons in large gauge multiplets at the 13 TeV LHC using final states with two or three leptons and fat-jets, demonstrating that such an approach can achieve discovery reach for masses up to approximately 2 TeV with the full High-Luminosity LHC dataset.
This paper proposes a novel search strategy using multivariate analysis to identify low-mass doubly-charged Higgs bosons decaying into boosted W-bosons as exotic jets and same-sign leptons, demonstrating that such particles could be directly probed using existing LHC Run 2 data to address the CDF W-boson mass anomaly.
This paper proposes that a compressed mass spectrum scenario in the type-II seesaw model, which has likely evaded previous LHC searches, can be effectively probed using multivariate analysis of same-sign dilepton events with low invariant mass on existing Run 2 and future HL-LHC data.
This paper proposes that an triplet scalar with hypercharge and a small mixing angle with the Standard Model Higgs can explain the 95 GeV diphoton excess through Drell-Yan production, predicting distinct kinematic signatures, an associated charged Higgs state near 95 GeV, and a positive shift in the W boson mass.
This review examines the evolution and current status of boosted top quark tagging methods, highlighting the shift from traditional cut-based strategies to modern machine learning approaches and their critical role in enhancing Beyond the Standard Model searches at the LHC.
This paper analyzes the theoretical constraints, electroweak precision predictions, and LHC phenomenology of the Standard Model extended by a real Higgs triplet, finding that while current searches exclude charged Higgs masses below 110 GeV, a specific signal region excess at 152 GeV suggests a statistically significant preference for a non-zero di-photon branching ratio of the neutral triplet Higgs.
This paper investigates the numerical challenges and convergence properties of self-interacting dark matter (SIDM) N-body simulations during the gravothermal collapse phase, demonstrating that high-resolution simulations with strict energy conservation can accurately model the formation of compact halos capable of explaining observations like the GD-1 stellar stream.
This paper presents a global fit of electroweak precision observables for dark photon models featuring both kinetic and mass mixing arising from an extended scalar sector, revealing that while moderate scalar vacuum expectation value ratios exclude dark photon masses between 40 GeV and 1 TeV, ample unconstrained parameter space remains for larger ratios.
This study analyzes the causal constraints of the Mueller-Israel-Stewart theory for heat flow in heavy-ion collisions, revealing that realistic conditions lead to causality-violating heat fluxes that suggest either an overestimation of transport coefficients or a breakdown of the fluid approximation.
This paper demonstrates that modified loop quantum cosmology (mLQC-I) naturally drives the Bianchi I universe toward isotropy by dynamically suppressing cosmological shear through a robust quantum-gravitational mechanism after the bounce, independent of the matter equation of state.
