Model independent analysis of $$ B^* \rightarrow P \ell {\bar{\nu }}_\ell $$ decay processes

A Model Independent Analysis of the Rare B Decay B →

The most general model-independent analysis of the rare B decay, B → X s l + l − , is presented. There are ten independent local four-Fermi interactions which may contribute to this process. The branching ratio, the forward-backward asymmetry, and the double differential rate are written as functions of the Wilson coefficients of the ten operators. We also study the correlation between the bran...

Model - independent analysis of p +

The pp hard bremsstrahlung reaction, p + p → pp(S0) + γ , in which the two protons in the final state are in the S0 state, is investigated theoretically. Here, the most general spin structure of the NN hard bremsstrahlung reaction, consistent with symmetry principles, is derived from a partial-wave expansion of this amplitude. Based on this spin structure, it is shown that there are only four i...

Model – independent analysis of the exclusive semileptonic B → π + π − l + l − decay

A model–independent analysis for the exclusive, rare B → π+π−l+l− decay is presented. The dependence of the various physically measurable asymmetries and CP violating asymmetry on the new Wilson coefficients is studied in detail. It is observed that different measurable quantiles are very sensitive to the different new Wilson coefficients, i.e., to the existence of new physics beyond standard m...
