Radiative Decays of Heavy-light Mesons and the $f_{H,H^*,H_1}^{(T)}$ Decay Constants

Autor: Pullin, Ben, Zwicky, Roman

The on-shell matrix elements, or couplings $g_{H H^*(H_1)\gamma}$, describing the $B(D)_q^* \to B(D)_q \gamma$ and $B_{1 q} \to B_q \gamma$ ($q = u,d,s$) radiative decays, are determined from light-cone sum rules at next-to-leading order for the firs

Charged and Neutral $\bar B_{u,d,s} \to \gamma$ Form Factors from Light Cone Sum Rules at NLO

Autor: Janowski, Tadeusz, Pullin, Ben, Zwicky, Roman

We present the first analytic ${\cal O}(\alpha_s)$-computation at twist-$1$,$2$ of the $\bar B_{u,d,s} \to \gamma$ form factors within the framework of sum rules on the light-cone. These form factors describe the charged decay $\bar B_u \to \gamma \e

Rare radiative B-meson decays

Autor: Pullin, Ben

This thesis explores various aspects of radiative B-meson decays. Such processes are phenomenologically interesting since the inclusion of the photon exposes the process to a wider array of effective operators than in the purely leptonic mode. There
