Quantum Tomography of Top Quarks as a Probe of Charge-Parity Violation
Eren Erdogan, Kirtimaan A. Mohan, Keping Xie +1
LHC measurements now reconstruct all fifteen parameters of the two-qubit spin density matrix, which amounts to a full quantum tomography of the pair. We show that this da…
Fate of Metastable Vacua in the Type-II Two-Higgs Doublet Model
Debtosh Chowdhury, Kirtimaan A. Mohan, Poulami Mondal +1
The scalar potential of the Two-Higgs-Doublet Model (2HDM) can admit multiple non-degenerate vacua due to the presence of the two Higgs doublets unlike the Standard Model (SM). For…
t-channel dark matter at the LHC -- a whitepaper
Chiara Arina, Benjamin Fuks, Luca Panizzi +67
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…
Radion Portal Freeze-Out Dark-Matter
R. Sekhar Chivukula, Joshua A. Gill, Kenn S. Goh +5
We show that, in a consistent model of a stabilized extra-dimensional theory, the radion can serve as a natural portal between ordinary matter and WIMP dark matter. With an effecti…
Limits on Kaluza-Klein Portal Dark Matter Models
R. Sekhar Chivukula, Joshua A. Gill, Kirtimaan A. Mohan +4
We revisit the phenomenology of dark-matter (DM) scenarios within radius-stabilized Randall-Sundrum models. Specifically, we consider models where the dark matter candidates are St…
Identifying the Quantum Properties of Hadronic Resonances using Machine Learning
Jakub Filipek, Shih-Chieh Hsu, John Kruper +2
With the great promise of deep learning, discoveries of new particles at the Large Hadron Collider (LHC) may be imminent. Following the discovery of a new Beyond the Standard model…
