Constraints on Vector-Like Top Dipole Interactions from Top-Associated Photon Measurements at the LHC
Mohammad Sahraei, Yasaman Hosseini, Mojtaba Mohammadi Najafabadi
Precision measurements of top-quark production with energetic photons provide a complementary probe of vector-like quarks with nonstandard radiative decays. We reinterpret the CMS…
Probing the Chern-Simons Portal at the HL-LHC through Displaced Vertices from W Boson Associated Production
Mohammad Nourbakhsh, Mojtaba Mohammadi Najafabadi
This study explores the Chern-Simons portal model, an extension of the Standard Model that introduces a massive neutral vector boson associated with a gauge symmetry.…
Reinterpretation and preservation of data and analyses in HEP
Jon Butterworth, Sabine Kraml, Harrison Prosper +145
Data from particle physics experiments are unique and are often the result of a very large investment of resources. Given the potential scientific impact of these data, which goes…
Machine Learning Approaches to Top Quark Flavor-Changing Four-Fermion Interactions in Trilepton Signals at the LHC
Meisam Ghasemi Bostanabad, Mojtaba Mohammadi Najafabadi
We explore the top quark flavor-changing 4-Fermi interactions ( and ) with scalar, vector, and tensor structures using machine learning models to analyze tri-lepton pro…
Constraining the top quark effective field theory using the top quark pair production in association with a jet at future lepton colliders
Reza Jafari, Parvin Eslami, Mojtaba Mohammadi Najafabadi +1
Our main aim in this paper is to constrain the effective field theory describing the top quark couplings through the jet process. The analysis i…
New Probes for Axion-like Particles at Hadron Colliders
Javad Ebadi, Sara Khatibi, Mojtaba Mohammadi Najafabadi
Axion-like particles (ALPs) appear from spontaneous global symmetry breaking in many extensions of the Standard Model (SM). In this paper, we find bounds on ALP () model paramet…
