CERN Proton Collision Dataset

Context

MultiJet primary dataset in AOD format from RunB of 2010. This dataset contains runs from 2010 RunB. The list of all validated runs, which must be applied to all analyses, can be found in http://opendata.cern.ch/record/1000
This file contains events from the MultiJet primary dataset from the CMS open data release, and computes the razor variables MR and Rsq, used in supersymmetric particle searches. More details on the razor variables can be found in Phys. Rev. D 90, 112001 (https://journals.aps.org/prd/pdf/10.1103/PhysRevD.90.112001)

Content

1. Run: The run number of the event.
2. Lumi: The lumi section of the event.
3. Event: The event number of the event.
4. MR: First razor kinematic variable, the MR variable is an estimate of an overall mass scale, which in the limit of massless decay products equals the mass of the heavy parent particle.
5. Rsq: Second razor kinematic variable, the Rsq variable is the square of the ratio R, which quantifies the flow of energy in the plane perpendicular to the beam and the partitioning of momentum between visible and invisible particles.
   6,7,8,9) E1,Px1,Py1,Pz1: The four-vector of the leading megajet (with the largest transverse momentum).
   10,11,12,13) E2,Px2,Py2,Pz2: The four-vector of the subleading megajet (with the largest transverse momentum).
6. HT: The scalar sum of the transverse momentum of the jets.
7. MET: The magnitude of the vector sum of the transverse energy of the particles in the event.
8. nJets: The number of jets with transverse momentum above 40 GeV.
9. nBJets: The number of b-tagged jets with transverse momentum above 40 GeV.
