Detailed analysis of possible new-physics effects in the semileptonic decay $B_{s} \to D_{s}^{(*)} I ¨ I^ˉ ½$

Mikhail A. Ivanov, Jignesh N. Pandya, Pietro Santorelli +4

We study the semileptonic decays $B_{s} \to D_{s}^{(*)} I ¨ I^ˉ ½$ 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 $I ¨ _{c J}$ , $h_{c}$ , $J / I ¨ $ , and $I ¨ (2 S)$ radiative decays in the framework of the covariant confined quark model. First, we exp…

Probing the ATOMKI X17 vector boson using Dalitz decays $V \to P e^{+} e^{-}$

Chien-Thang Tran, Mikhail A. Ivanov, Anh-Tuyet T. Nguyen

Recent anomalies observed in $e^{+} e^{-}$ nuclear transitions of $^{8} Be$ , $^{4} He$ , and $^{12} C$ by the ATOMKI collaboration may hint at the existence of a v…

Polarization observables in semileptonic $V \to P$ decays of quarkonia

Chien-Thang Tran, Mikhail A. Ivanov, Ngoc-Dung Nguyen +1

We investigate the weak semileptonic decays of the charmonium $J / I ¨ $ and bottomonium $I^¥ (1 S)$ into a pseudoscalar meson, namely, the $J / I ¨ \to D_{(s)} ℓ I^ˉ ½_{ℓ}$ and $Î¥(1S)\to…

Study of the semileptonic decays $I^¥ (1 S) \to B_{(c)} ℓ I^ˉ ½_{ℓ}$

Chien-Thang Tran, Mikhail A. Ivanov, Pietro Santorelli +1

We study the exclusive semileptonic decays $I^¥ (1 S) \to B_{(c)} ℓ I^ˉ ½_{ℓ}$ , where $ℓ = e, I^¼, I ¨ $ . The relevant hadronic form factors are calculated using the Covariant Confine…
