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 model where dark matter consists of heavy 't Hooft-Polyakov monopoles produced via a thermal phase transition, requiring a specific parameter window where a light dark fermion suppresses monopole abundance while satisfying dark radiation constraints, thereby predicting observable gravitational waves and signals despite being undetectable by current conventional experiments.
This paper extends a transformer-based generative modeling approach, previously used to establish the fundamental performance limits for boosted top-quark jet tagging, to W, Z, and Higgs-to-gluon jets, revealing that the gap between current machine-learning taggers and the theoretical optimal limit is strongly jet-dependent and significantly smaller for these more challenging tasks.
This paper proposes an inflationary mechanism driven by flux stationarity near Calabi-Yau Hodge boundaries, which stabilizes moduli without extra flux costs and directly links internal geometric properties to observable primordial tensor perturbations that align with current CMB limits and future LiteBIRD and CMB-S4 targets.
This paper proposes a new class of CP sum rules expressed directly in terms of decay widths within the exact U-spin limit (), extending beyond traditional amplitude-level analyses to include matched partial waves, spin observables, angular moments, and nonpairwise cases.
This paper investigates inflation driven by dynamical torsion in gravity theories, demonstrating that anomaly-induced decays into gauge bosons and Higgs-involved three-body processes provide a non-vanishing inflaton decay width, thereby establishing a natural lower bound on the reheating temperature.
This paper investigates the production and detection prospects of light scalar sgoldstinos (with masses from the dimuon threshold to a few GeV) at the SND@HL-LHC experiment, reviewing their effective interactions and constraints while presenting sensitivity estimates that highlight the critical importance of muon-antimuon separation efficiency for dimuon signal searches.
This paper proposes a predictive framework where dark photons serve as dark matter produced via the perturbative decay of a stochastically misaligned dark Higgs field, identifying a viable parameter space for their mass and coupling that is constrained by structure formation and isocurvature fluctuations while remaining testable through future cosmological observations and direct detection experiments.
This paper proposes "lens stochastic diffraction" (LSD), a method that detects the collective, correlated fluctuations of secondary gravitational-wave images caused by intervening compact objects to statistically probe dark matter halos and supermassive black holes with significantly higher sensitivity than traditional individual lensing searches.
This paper estimates the sensitivity of Wilson coefficients for lepton flavor-violating dimension-six operators at a proposed muon collider by computing signal significance and measurement errors for effective couplings at center-of-mass energies of 3 and 10 TeV using the optimal observable method.
This paper demonstrates that various quantum information measures, including magic, trace distance, and fidelity distance, offer distinct and complementary sensitivities to new physics in the top quark sector within the Standard Model Effective Field Theory, highlighting the importance of employing multiple such metrics to effectively probe beyond-Standard-Model phenomena.
