Weak PhaseγUsing Isospin Analysis and Time-Dependent Asymmetry inBd→KSπ+π−

Weak Phase γ Using Isospin Analysis and Time Dependent Asymmetry in B d →

Abstract We present a method for measuring the weak phase γ using isospin analysis of three body B decays into Kππ channels. Differential decay widths and time dependent asymmetry in Bd → KSπ π mode needs to be measured into even isospin ππ states. The method can be used to extract γ, as well as, the size of the electroweak penguin contributions. The technique is free from assumptions like SU(3...

Spin and Isospin Asymmetry, Equation of State and Neutron Stars

In the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. We have also investigated the structure of neutron stars. According to our results, the spin asymmetry stiens the equation of state and leads to high mass for the neutron star.

A Study of Time - Dependent CP Asymmetry

We present our first study of the time-dependent CP-violating asymmetry in B 0 → J/ψ π 0 decays using e + e − annihilation data collected with the BABAR detector at the Υ (4S) resonance during the years 1999–2002 at the PEP-II asymmetric-energy B Factory at SLAC. With about 88 million BB pairs, our preliminary results for the coefficients of the cosine and sine terms of the CP asymmetry are C J...
