Probing New Forces with Nuclear Clocks
Cédric Delaunay, Seung J. Lee, Roee Ozeri +3
Clocks based on nuclear isomer transitions promise exceptional stability and precision. The low transition energy of the thorium-229 isomer makes it an ideal candidate, as it has b…
Light scalar beyond the Higgs mixing limit
Cédric Delaunay, Teppei Kitahara, Yotam Soreq +1
We explore the possibility that the interactions of a light scalar singlet, which mixes with the Standard Model~(SM) Higgs, also receive other UV contributions of comparable size.…
Impact of CPV phases on flavour violating and decays
E. Pinsard, A. Abada, J. Kriewald +2
Standard Model extensions via heavy neutral leptons lead to modifications in the lepton mixing matrix, including new Dirac and Majorana CP violating phases. Here we consider the ro…
Lepton Flavor Universality tests through angular observables of decay modes
Damir Becirevic, Marco Fedele, Ivan Nisandzic +1
We discuss the possibility of using the observables deduced from the angular distribution of the decays to test the effects of lepton flavor universalit…
A Dark Matter Interpretation of the ANITA Anomalous Events
Lucien Heurtier, Yann Mambrini, Mathias Pierre
The ANITA collaboration recently reported the detection of two anomalous upward-propagating extensive air showers exiting the Earth with relatively large emergence angles and energ…
Probing low energy scalar leptoquarks by the leptonic and couplings
Pere Arnan, Damir Becirevic, Federico Mescia +1
We compute the generic one-loop contribution involving scalar leptoquarks (LQ) to the and leptonic decay widths. In our computation we include for the first time the finite…
