CompHEP is a package for automatic calculations of elementary particle decay and collision properties in the lowest order of perturbation theory (the tree approximation). The main idea prescribed into the CompHEP is to make available passing on from the Lagrangian to the final distributions effectively with a high level of automation.

  1. Baryon-dark matter coincidence in Randall-Sundrum Model

    hep-ph 2026-01 conditional novelty 6.0 of 10

    Graviton- and radion-mediated freeze-in in a Randall-Sundrum model can match the observed dark matter relic abundance, and TeV-scale resonant leptogenesis through the same portals can match the observed baryon asymmet...

  2. Reconstruction of angular correlations in the associated top quark and the dark matter mediator production

    hep-ph 2025-04 conditional novelty 6.0 of 10

    A normalizing-flow neural network reconstructs the momenta of the neutrino and dark mediator in single top quark production and reproduces a top-quark spin-correlation variable more accurately than a multilayer perceptron.

  3. Scalar dark matter, Neutrino mass and Leptogenesis in a $\rm U(1)_{B-L}$ model

    hep-ph 2019-08 conditional novelty 4.0 of 10

    A U(1)B-L model with four anomaly-cancelling fermions can satisfy dark matter relic density and direct detection bounds, neutrino oscillation data, and the observed baryon asymmetry through resonant leptogenesis.

  4. A light CP-odd Higgs boson of the MSSM Higgs sector extended by dimension-six operators

    hep-ph 2019-08 conditional novelty 4.0 of 10

    A dimension-six extended MSSM can host a 28 GeV CP-odd Higgs with a 125 GeV SM-like Higgs, but predicted muon-pair rates fall short of the CMS excess.

  5. Correlative study of flavor anomalies and dark matter in the light of scalar leptoquark

    hep-ph 2024-09 unverdicted novelty 3.0 of 10

    A U(1)_{Le-Lμ} extended SM with scalar leptoquark explains b→s anomalies via Z', leptoquark and new fermions while the lightest neutral fermion serves as DM, with constraints analyzed from B decays and DM observables.
