The Honey Bee Network has helped provide a sort of loose platform to converge creative, but uncoordinated individuals across not only Indian states having varying cultural, linguistic and social ethos, but also in 75 other countries around the world. What the Network is trying to do in a rather quiet manner may transform the way the resources—in which poor(More)
In the presence of penguin contributions, the indirect CP asymmetry in B(t) → ππ measures sin(2α + 2θ), where 2θ parametrizes the size of the penguin “pollution.” We present a new upper bound on |2θ|, involving also the measurement of B → ππ, along with an upper bound on or a measurement of BR(B → ππ)+BR(B0 → ππ). The new bound is stronger than those(More)
The short-distance Hamiltonian describing b → s(d)e−e+ in the standard model is used to obtain the decay spectrum of B̄ → K−π+e−e+ and B̄ → π−π+e−e+, assuming the Kπ and ππ systems to be the decay products of K and ρ respectively. Specific features calculated are (i) angular distribution of K (or π) in the K−π+ (or π−π+) centre-of-mass (c.m.) frame; (ii)(More)
The short-distance Hamiltonian describing b → s(d)e−e+ in the standard model is used to obtain the decay spectrum of B̄ → K−π+e−e+ and B̄ → π−π+e−e+, assuming the Kπ and ππ systems to be the decay products of K∗ and ρ respectively. Specific features calculated are (i) angular distribution of K− (or π−) in the K−π+ (or π−π+) centre-of-mass (c.m.) frame; (ii)(More)
We present a method for measuring the weak phase gamma using isospin analysis of three body B decays into Kpipi channels. Differential decay widths and time-dependent asymmetry in B(d)-->K(S)pi(+)pi(-) mode needs to be measured into even isospin pipi states. The method can be used to extract gamma, as well as the size of the electroweak penguin(More)
We present a technique to determine the CP violating phases, as well as, the lifetime differences of the mass eigenstates for both Bd and Bs, by considering correlated BB̄ pairs produced at the Υ resonances. We do not require a detailed time dependent study, but only partial time integrated rates, with the tag time, either preceding or following the decay(More)
We study the contributions of the CP violating anomalous WWγ interactions to b → sll. We obtain cutoff independent results on κ̃ and λ̃, by constructing an asymmetry for the process B → Kll, where the B and B̄ events are added. We show that a sample of 10 B → Kee events can yield a bound, |κ̃| < 0.42 at 90% C.L., which is much tighter than the recent(More)
We propose a method to determine the angle γ = arg(Vub), using the B → D∗V (V = K∗, ρ) modes. The D∗ is considered to decay to Dπ. An interference of the B → D∗0V and B → D∗0V amplitudes is achieved by looking at a common final state f , in the subsequent decays of D0/D0. A detailed analysis of the angular distribution, allows determination, not only of γ(More)
The b → d penguin amplitude receives contributions from internal u, c and t-quarks. We show that it is impossible to measure the weak phase of any of these penguin contributions without theoretical input. However, a single assumption involving the hadronic parameters makes it possible to obtain the weak phase and test for the presence of new physics in the(More)
Surgical management of advance aortoiliac occlusive disease is time-tested and a widely practiced strategy, particularly when there is significant coronary artery disease associated with aortoiliac occlusive disease. The technological advances in the field of percutaneous techniques have facilitated the use of nonsurgical endovascular alternatives for(More)
