Strings , and Meson Factories
Spontaneous breaking of CPT is possible in string theory. We show that it can arise at a level within reach of experiments at meson factories currently being built or designed. For φ, B, and τ-charm factories, we discuss the likely experimental string signatures and provide estimates of the bounds that might be attained in these machines.
متن کاملCpt Violation , Strings , and Neutral - Meson Systems
Symmetry under the discrete transformation CPT is a general theoretical condition holding for local relativistic field theories of point particles [1]-[7]. This symmetry has been investigated experimentally under different circumstances and to a high degree of precision [8]. The broad theoretical validity of CPT symmetry for particles and the availability of high-precision tests makes CPT viola...
متن کاملT and CPT in B - Factories 1
For the B d meson system, CP, T and CPT indirect violation can be described using two physical parameters, ε and δ. The traditional observables based on flavour tag and used in the kaon system, are not helpful in the B d case, and new asymmetries have to be introduced. Here such alternative observables, based on CP tag, are presented, together with the first estimation on the sensitivity that c...
متن کاملCPT-violating Observables in Meson Decays
We present a general model-independent and rephase-invariant formalism that cleanly relates CP and CPT noninvariant observables to the fundamental parameters. Different types of CP and CPT violations in the K0-, B0-, B0 s and D 0-systems are explicitly defined. Their importance for interpreting experimental measurements of CP and CPT violations is emphasized. In particular, we show that the tim...
متن کاملStrings in meson and baryon physics
The relativistic string with massive ends (the meson model) and four various string baryon models: q-qq, q-q-q, Y and ∆ are considered. In particular, the rotational motions for all these systems are applied to describing the leading Regge trajectories, and also the classical dynamics beyond the usual rectilinear string rotations is studied. For the string meson model the two types of quasirota...
