Delta t-dependent equal-sign dilepton asymmetry and CPTV effects the symmetry of the B-0-(B)over-bar(0) entangled state
In this paper we discuss experimental consequences of a novel kind of CPT violation which would manifest itself in the symmetry of the entangled initial state of B-0 and (B) over bar (0) through their loss of indistinguishability. The 'wrong' symmetry component is proportional to omega. We focus our theoretical study on the Delta t-dependence of observables concerning equal-sign dilepton events for which the intensity vanishes at Delta t = 0 in absence of omega. We find that the charge asymmetry, A(sl), acquires a Delta t-dependence linear in !, whose relative importance appears on specific regions of time still unexplored. We also do a statistical analysis for the measurements here propose…
CPT violation in entangled BO-anti-BO states and the demise of flavour tagging
We discuss the demise of flavour tagging due to the loss of the particle-antiparticle identity of neutral B-mesons in the Einstein-Podolsky-Rosen correlated states. Such a situation occurs in cases where the CPT operator is ill-defined, as happens, for example, in quantum gravity models with induced decoherence in the matter sector. The time evolution of the perturbed B0-B0bar initial state, as produced in B-factories, is sufficient to generate new two-body states. For flavour specific decays at equal times, we discuss two definite tests of the two body entanglement: (i) search for the would-be forbidden B0 B0 and B0bar B0bar states; (ii) deviations from the indistinguishable probability be…
