Detailed analysis of possible new-physics effects in the semileptonic decay
Mikhail A. Ivanov, Jignesh N. Pandya, Pietro Santorelli +4
We study the semileptonic decays as a promising probe for new physics (NP) beyond the standard model (SM). The extension of the SM is done through the i…
Revisiting radiative transitions of charmonium states in covariant confined quark model
Aidos Issadykov, Mikhail A. Ivanov, Dang-Khoa N. Nguyen +3
We calculate the amplitudes and branching fractions of , , , and radiative decays in the framework of the covariant confined quark model. First, we exp…
Probing the ATOMKI X17 vector boson using Dalitz decays
Chien-Thang Tran, Mikhail A. Ivanov, Anh-Tuyet T. Nguyen
Recent anomalies observed in nuclear transitions of , , and by the ATOMKI collaboration may hint at the existence of a v…
Polarization observables in semileptonic decays of quarkonia
Chien-Thang Tran, Mikhail A. Ivanov, Ngoc-Dung Nguyen +1
We investigate the weak semileptonic decays of the charmonium and bottomonium into a pseudoscalar meson, namely, the and $Î¥(1S)\to…
