Special Issue on CP Violation as a probe of New Physics beyond Standard Model


LETTERS IN HIGH ENERGY PHYSICS


Call for Papers

Charge Conjugation Parity (CP) symmetry is not a symmetry of nature and it is not even an approximate symmetry. In fact, CP Violation (CPV) is an essential ingredient to understand the matter-antimatter asymmetry in the Universe. At the moment, CPV has been observed only in non leptonic decays of kaons, B and Bs and recently in D mesons. In the leptonic sector, the T2K collaboration has reported a measurement that shows an indication of CPV in the neutrino sector at 3 sigma confidence level. In the standard model (SM) there is a single phase in the CKM matrix that is responsible for all CP violating phenomena. It is quite likely there can be new CP violating weak phases in extensions of the SM with new complex couplings. Hence, CPV measurements are excellent probes of beyond SM physics. CP Violating phenomena can be explored in the quark and in the lepton sector. The presently running experiments like Belle II and LHCb and their next upgraded phases may offer unprecedented opportunities to observe new CP violating phenomena. In the lepton sector, experiments might reveal new sources of CP violation.
Topics may include but are not limited to:

  1. CP Violation in the meson sector:
    1. CP violation in the meson mixing.
    2. Direct CP Violation in meson decays.
  2. CP violation in the lepton sector.
  3. CP violation in the combined sectors.
