Mixing angles of Xi Q-Xi(1)Qin heavy quark effective theory
The Heavy Quark Effective Theory provides a systematic method to estimate a mixing angles of hadron states in a heavy quark, such as charm quark (c) and bottom quark (b). Using this method, we can estimate the mixing angles of the baryons Xi Q- Xi Q. The mixing angles between Xi Q and Xi Q are given...

| Zusammenfassung: | The Heavy Quark Effective Theory provides a systematic method to estimate a mixing angles of hadron states in a heavy quark, such as charm quark (c) and bottom quark (b). Using this method, we can estimate the mixing angles of the baryons Xi Q- Xi Q. The mixing angles between Xi Q and Xi Q are given by |theta b | = 4.51x25e6; +/- 0.79x25e6; for the Q = b case and |theta c| = 8.12x25e6; +/- 0.80x25e6; for the Q = c case.
