Tagging of B-Bbar Using B**-> B pi Decay

A new tagging method to measure the angle beta in the unitarity triangle by the decay B -> J/psi K0s has been studied. The nature of the b quark is known by the charge of the emitted pion in the B** decay : B**+ -> B0d pi+. The expected precision of the CMS detector measurement for ang...

description A new tagging method to measure the angle beta in the unitarity triangle by the decay B -> J/psi K0s has been studied. The nature of the b quark is known by the charge of the emitted pion in the B** decay : B**+ -> B0d pi+. The expected precision of the CMS detector measurement for angle beta with this method has been evaluated to be delta ( sin 2 beta) = 0.022.
