Laser-induced breakdown spectroscopy for branching ratio and atomic lifetime measurements in singly-ionized neodymium and gallium☆

Branching Ratio and Form Factor Measurements of 0 Beta Decay

We present a branching ratio measurement for the beta decay of neutral Cascade hyperon, 0 ! + e e , using the KTeV detector at Fermilab. We used the principal decay mode of 0 ! 0 where ! p , as the ux normalization mode. The status of the measurement of the ratio of the axial-vector to vector coupling (g1/f1) for the Cascade beta decay will also be discussed. Furthermore, we present the prelimi...

Branching ratio of the H-(n=2) shape resonance.

Branching Ratio

The / e π ν π μν → → branching ratio provides unique access to physics beyond the Standard Model due to the extraordinary precision of its SM prediction and the potential for highly accurate measurements. The motivation and prospects for new measurements presently underway at PSI and TRIUMF will be discussed.

Branching Ratio Anomalies from R-Parity Violation

The branching ratios for the neutral and charged B decay channels to ηK and ηK are well above the Standard Model expectations. Moreover, the mixing-induced CP asymmetry in B → φKS is incompatible to that found in B → J/ψKS . We investigate whether a flavourspecific tree-level b → sss operator coming from R-parity violating supersymmetry can resolve both these discrepancies, without jeopardizing...
