Executive Summary : | The quest of particle physics, in general, and heavy flavor physics, in specific, is to understand the fundamental laws of nature to minimize the gaps of our understanding. The maximum effort in this direction is dedicated to the test of the standard model (SM) and search for new physics “beyond Standard Model” (BSM). The New Physics can be approached in two ways, the first one is directly looking for beyond Standard Model particles, while the other is an indirect search for New Physics contributions in the observed decays of heavy flavor particles by CMS, ATLAS and LHCb. Furthermore, the B-factories have provided precision measurement properties and decays of heavy flavor particles that pose serious challenges to current theoretical and phenomenological models of heavy flavor physics. For proper understanding of heavy flavor dynamics, i) testing/expansion of theoretical and phenomenological hypotheses including the hadronic effects within the SM and ii) more precise measurements of particle properties and decays for new physics (BSM), is necessary. The proposed work aims to study weak radiative decays of heavy flavor (c, b) mesons where exclusive processes are expected to provide insight to heavy flavor dynamics. These decays provide a clean test to basic quantum field theory tools such factorization theorems, understanding of perturbative and non-perturbative regimes, magnitude of the Cabibbo–Kobayashi–Maskawa (CKM) parameters, operator product expansion (inclusive processes) etc., and are considered as a window to new physics. |
