Sharpening the Signature of the Type-II 2HDM at the LHC through Advanced Machine Learning

W. Esmail, A. Hammad, S. Moretti

The decay signature has been highlighted as possibly being the first testable probe of the Standard Model (SM) Higgs boson discovered in 2012 () interacting with…

Dark photon and dark mediated meson decays

Alakabha Datta, A. Hammad, Danny Marfatia +2

We study flavor changing neutral current decays of and mesons in the dark model, with the dark photon/dark mass between 10 MeV and 2 GeV. Although the model pr…

Riemannian Data preprocessing in Machine Learning to focus on QCD color structure

A. Hammad, Myeonghun Park

Identifying the quantum chromodynamics (QCD) color structure of processes provides additional information to enhance the reach for new physics searches at the Large Hadron Collider…

Explaining excesses in four-leptons at the LHC with a double peak from a CP violating Two Higgs Doublet Model

Stefan Antusch, Oliver Fischer, A. Hammad +1

Extended scalar sectors with additional degrees of freedom appear in many scenarios beyond the Standard Model. Heavy scalar resonances that interact with the neutral current could…

The Dark and Sterile Neutrinos Behind Current Anomalies

A. Hammad, Ahmed Rashed, S. Moretti

We show how, in the extension of the SM (BLSM) with an Inverse Seesaw (IS) mechanism for neutrino mass generation, a light state with moderate couplings to SM objects, h…

Testing CP Properties of Extra Higgs States at the HL-LHC

Stefan Antusch, Oliver Fischer, A. Hammad +1

Extra Higgs states appear in various scenarios beyond the current Standard Model of elementary particles. If discovered at the LHC or future colliders, the question will arise whet…
