Rare Decays as Window to New Physics
L. M. Sehgal
Rare decays of K mesons are reviewed from the perspective of testing the ``ones'' and ``zeros'' of the standard model. Decays K^+ -> pi^+ nu anti-nu and K_L -> pi^0 nu anti-nu prob…
CP- and T-Violation in the Decay K_L -> pi+ pi- e+ e- and Related Processes
L. M. Sehgal
I review the theoretical basis of the prediction that the decay K_L -> pi+ pi- e+ e- should show a large CP- and T-violation, a prediction now confirmed by the KTeV experiment. The…
Day-Night Effect for Solar Neutrinos: Coherent versus Incoherent Regeneration in the Earth
J. van Leusen, L. M. Sehgal

CP Violation in Selected B Decays
F. Krüger, L. M. Sehgal
We summarize the results of two papers in which we have studied CP violation in inclusive and exclusive decays b -> d e^+e^-. Two CP-violating effects are calculated: the partial r…
Remarks on the Inclusive Decays and
M. Gremm, G. Köpp, F. Krüger +1
We consider the effects of quark-binding on the angular distribution and polarization characteristics of the inclusive decays and $Λ_b \to X_c l \bar{\n}_l$ $(l=e,…
