Hlt2RD_BToHHGamma_GammaToEE_Incl

BToHHGamma_GammaToEE_Incl_line(name='Hlt2RD_BToHHGamma_GammaToEE_Incl', prescale=1, persistreco=True)[source]

Definition of B->HHgammaEE HLT2 line.

Final states built are (omitting intermediate resonances):

  1. B0 -> K+ K- (gamma -> e+ e-)

  2. [B+ -> K+ KS0 (gamma -> e+ e-)]cc

  3. [B+ -> K+ Lambda0 (gamma -> e+ e-)]cc

  4. [B+ -> K+ Lambda~0 (gamma -> e+ e-)]cc

This line first combines 2 hadrons, where at least one of them must be charged. The result is combined with a “converted” photon, which is built from an electron-positron pair with small invariant mass, to build a B candidate. The b candidates are then given to a BDT to further reduce the output rate. These radiative inclusive lines are inclusive in the sense that no PID is used when selecting the hadrons, and no mass requirements are applied either to the K*, D*, or B candidates
