Invited Speaker / Conférencier invité

Physics beyond the Standard Model (BSM) affects low-energy processes such as meson decays through loop-suppressed contributions. Precision physics to separate loop-level corrections are therefore considered vital for the discovery of BSM physics at the intensity frontier. I will describe the current status of research in the field of $B$ decays, concentrating on its role in establishing the...

The forward backward asymmetry distribution for the rare dileptonic decay $B\to K^{\ast }{\mu }^{+}{\mu }^{-}$ in the region below the $J/\psi$ resonance is calculated. We use the form factors for $B\to K^{\ast }$ transition which are predicted by the anti-de Sitter/Quantum Chromodynamics (AdS/QCD) correspondence. We compare our results with those obtained from QCD sum rules.

Oral (Non-Student) / orale (non-étudiant)

We compute the isospin asymmetry distribution in the rare dileptonic decay B→K*μ+μ-, in the dimuon mass squared (q2) region below the J/Ψ resonance, using nonperturbative inputs as predicted by the anti–de Sitter/quantum chromodynamics correspondence and by sum rules. We predict a positive asymmetry at q2=0 which flips sign in the region q2∈[1,2]  GeV2 to remain small (≤2%) and negative for...

Invited Speaker / Conférencier invité

Belle II will probe the 'flavour sector' of particle physics at the high-luminosity SuperKEKB e+e- collider, located at the KEK laboratory in Japan. Accelerator commissioning will start in 2016, with the goal of collecting 50 inverse attobarns of data by 2024, which is thirty times the combined integrated luminosity of the two previous generation B-factories, PEP-II at SLAC and KEKB at KEK....

Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)

To prepare for the large backgrounds expected to be present in the Belle II detector from the SuperKEKB e+e- collider, the radiation hardness of several ($5\times 5\times 30{\text{cm}}^3$) thallium doped cesium iodide scintillation crystals are studied to accumulated $\sim 1$ MeV photon doses of up to 1000 Gray. The sample set of crystals studied consists of 2 spare crystals from the Belle...
