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 Violation in the Decays B -> K Kbar in the Presence of D Dbar <-> K Kbar Mixing
S. Barshay, L. M. Sehgal, J. van Leusen
We have recently shown that the large direct CP violation observed in the decay B^0 -> pi^+ pi^-, and the enhanced branching ratio for B^0 -> pi^0 pi^0, can be understood by invoki…
Wrong-Helicity Electrons in Radiative Muon Decay
V. S. Schulz, L. M. Sehgal
We have studied in detail the spectrum of the decay mu^- -> e^- anti-nu_e nu_mu gamma as a function of the electron helicity, and verify the prediction of Sehgal (Phys.Lett. B569,…
Direct CP Violation in B-+ -> pi-+ omega, pi-+ rho0, pi0 rho-+, and in B-bar0(B0) -> pi-+ rho+- With an Enhanced Branching Ratio for pi0 rho0
Saul Barshay, Georg Kreyerhoff, Lalit M. Sehgal
We present a novel dynamics for generating sizable CP-violating asymmetries in the decays of charged , and in . T…
Stokes Vector of Photon in the Decays B^0 -> rho^0 gamma and B^0 -> K^* gamma
L. M. Sehgal, J. van Leusen
We consider a model for the decay Bbar^0 -> rho^0 gamma in which the short-distance amplitude determined by the Hamiltonian describing b -> d gamma is combined with a typical long-…
Large Direct CP Violation in B^0 -> pi^+ pi^- and an Enhanced Branching Ratio for B^0 -> pi^0 pi^0
S. Barshay, L. M. Sehgal, J. van Leusen
Recent measurements of B^0 -> pi pi decays reveal two features that are in conflict with conventional calculations: the channel B^0 (Bbar^0) -> pi^+ pi^- shows a large direct CP-vi…
