[Rivet] correction on ATLAS_2011_I944826 routine

[Sercan Sen]

Hello,

I think there is a small correction needed on ATLAS_2011_I944826 routine.

It applies charged final states projection for the particles in |\eta| < 2.5, however, search for the hits in MBTS rapidity region 2.09 < |\eta| < 3.84. see below.. In this case, trigger cut is limited to the 2.09<|\eta|<2.5.

      ChargedFinalState  cfs(-2.5, 2.5, 100*MeV);
      addProjection(cfs, "CFS");

      const ChargedFinalState& cfs = applyProjection<ChargedFinalState>(event, "CFS");

      // ATLAS MBTS trigger requirement of at least one hit in either hemisphere
      const ChargedFinalState& cfs = applyProjection<ChargedFinalState>(event, "CFS");
      int n_mbts = 0;
      foreach (const Particle& p, cfs.particles()) {
        const double eta = fabs(p.momentum().eta());
        if (inRange(eta, 2.09, 3.84)) n_mbts++;
      }

      if (n_mbts < 1) {
        MSG_DEBUG("Failed trigger cut");
        vetoEvent;
      }

Cheers,
Sercan
