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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper demonstrates that a classical, exactly solvable model of the electron proposed by Bialynicki-Birula successfully reproduces the leading non-analytic terms in the small-t expansion of the energy-momentum tensor form factors for a charged particle in QED, while also offering insights into the regularized proton D-term.
This paper introduces a TeV-scale Type-V Seesaw model featuring new fermionic multiplets that generate Majorana neutrino masses via a dimension-9 operator, and it investigates its phenomenological implications by constraining Yukawa couplings through lepton flavor violation limits and establishing 95% CL mass bounds for the new particles using CMS multilepton data.
This paper conducts a comprehensive study of the Type-II see-saw mechanism with a non-degenerate triplet Higgs spectrum, deriving updated 95% CL lower limits on the doubly charged scalar mass that exceed current LHC constraints by 50–230 GeV while identifying unconstrained parameter regions and proposing improved search strategies for the high-luminosity phase.
This paper investigates a cosmological scenario where mini primordial black holes, formed during a stiff fluid domination phase in runaway inflation models, evaporate to reheat the early universe, while also predicting a compound gravitational wave signal, potential dark energy contributions, and the existence of PBH remnants.
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.
