B-physics trigger: add two chains for cascade decay of the B_c+ to J/psi D*+

Vladimir Lyubushkin requested to merge lyubushk/athena:master-bBmumux into master

Two last chains for bBmumux have been added. B_c+ -> J/psi(-> mu+ mu-) D*+(-> D0(-> K- pi+) pi+)

  • 'HLT_2mu4_bBmumux_BcmumuD0Xloose_L12MU3V' for partially reconstructed B_c+, i.e. pion from from D*+ decay is lost
  • 'HLT_2mu4_bBmumux_BcmumuDstarloose_L12MU3V' for fully reconstructed B_c+

It has been tested on a small private sample containing 15000 of signal B_c+ to J/psi D*+ events. No problems were spotted.
