$B \to T$ transition form factors in light-cone sum rules

T. M. Aliev, H. Dag, A. Kokulu +1

We present a new calculation of the semileptonic tree-level and flavor-changing neutral current form factors describing $B$ -meson transitions to tensor mesons $T=D_2^*,K_2^*,a_2,f_…

$B \to P$ and $B \to V$ Form Factors from $B$ -Meson Light-Cone Sum Rules beyond Leading Twist

Nico Gubernari, Ahmet Kokulu, Danny van Dyk

We provide results for the full set of form factors describing semileptonic $B$ -meson transitions to pseudoscalar mesons $π$ , $K$ , $D ˉ$ and vector mesons $ρ$ , $K^{*}$ , $\bar{D}^…

The Belle II Physics Book

E. Kou, P. Urquijo, W. Altmannshofer +524

We present the physics program of the Belle II experiment, located on the intensity frontier SuperKEKB $e^{+} e^{-}$ collider. Belle II collected its first collisions in 2018, and is ex…

The \bar{B} \to X_s γγdecay: NLL QCD contribution of the Electromagnetic Dipole operator O_7

Ahmet Kokulu

We calculate the set of O(α_s) corrections to the double differential decay width dΓ_{77}/(ds_1 \, ds_2) for the process \bar{B} \to X_s γγoriginating from diagrams involving the e…
