چکیده
We study the neutral current flavour changing rare decay mode B → Kγγ within the framework of Standard Model, including the long distance contributions. It is found that these long distance contributions can be larger than the short distance contribution. —————————————————————————————————— We have corrected a sign error in one of the terms contributing to the Irre-ducible (short-distance) contribution in our program. The revised estimates agree well with the ones given in a recent paper [12]. ——————————————————————————————————

We study the neutral current flavour changing rare decay mode B → Xs+ missing energy within the framework of theories with large extra spatial dimensions. The corresponding Standard Model signature is B → Xs + νν̄. But in theories with large extra dimensions, it is possible to have scalars and gravitons in the final state making it quite distinct from any other scenario where there are no gravit...

Calculations of η → ππγγ decay in Generalized chiral perturbation theory are presented. Tree level and next-to-leading corrections are involved. Sensitivity to violation of the Standard counting is discussed.

CP violating effects in the single top quark production via flavour changing neutral current (FCNC) reactions e + e − → t¯ q and e + e − → ¯ tq (here q refers to charm and up quarks) are studied. The effective Lagrangian description of the FCNC interactions is used. A numerical analysis is performed for some next linear colliders. CP violating asymmetries for the number of q and ¯ q quarks are ...
