Description
One of the outstanding problems in physics is to explain the baryon-anti-baryon
asymmetry observed in nature. According to the well-known Sakharov criterion for
explaining the observed baryon-anti-baryon asymmetry, it is essential that CP
violation exist in the baryon sector. However, CP violation has only been
observed in mesons decays and is yet to be convincingly demonstrated in baryons
decays. A critical test of the standard model (SM) goes beyond just observing
CP violation in baryons and requires that it be measured in baryon decays as
well, in order to verify that it agrees with that measured in the meson decays.
In this letter we propose a new method to measure CP violating phase in
$b$-baryons, using interference arising implicitly due to Bose symmetry
considerations of the decaying amplitudes.
