Angular observables and branching ratio for $B_{s} \to ϕ ℓ^{+} ℓ^{-}$ decay

Aidos Issadykov

In this paper, an analysis of the $B_{s} \to ϕ ℓ^{+} ℓ^{-}$ rare decay is presented within the framework of the covariant confined quark model. The $B_{s} \to ϕ$ transition form factors…

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 $χ_{c J}$ , $h_{c}$ , $J / ψ$ , and $ψ (2 S)$ radiative decays in the framework of the covariant confined quark model. First, we explic…

A realistic photon spectra in polarized γγ processes in SANCphot

Sergey G. Bondarenko, Aidos Issadykov, Lidia V. Kalinovskaya +1

This work presents an approach to improve the precision of polarized photon-photon collisions simulation implemented in the SANCphot package. The basic linear Compton approximation…

Two-loop QED/QCD corrections for polarized $γ γ \to γ γ$ process in SANCphot

Serge Bondarenko, Aidos Issadykov, Lidia Kalinovskaya +2

The new version of the SANCphot integrator has been prepared for fast and stable numerical calculations up to two loops for polarized light-by-light scattering. One-loop modules ba…

$B_{c}^{*}$ meson parameters and radiative decay width within the covariant confined quark model

Aidos Issadykov, Sayabek K. Sakhiyev

In this work we tried to predict the parameters of $B_{c}^{*}$ meson. Simple assumptions gave us following parametres $m_{B_{c}^{*}} = 6329 \pm 10$ MeV and $f_{B_{c}^{*}} = 535.5 \pm 57.8$ …

$B \to K^{(*)} ν ν ˉ$ in covariant confined quark model

Aidos Issadykov, Mikhail A. Ivanov

We study the $B \to K^{(*)} ν ν ˉ$ decays within the Standard Model (SM) by using the relevant transition form factors obtained from the covariant confined quark model (CCQM) d…
