Abstract
Physics beyond the Standard Model (BSM) may be unveiled by studying events with a high number of outgoing jets, produced at the LHC with energies above the TeV scale (energetic multi-jet events). Such events are dominated by QCD processes, where the calculations rely on some sort of approximation. Therefore, it is important to develop a robust approach for modeling such events that could probe the existence of BSM signals. In this note, jet spatial distributions in energetic multi-jet processes were compared using several state-of-the-art MC event generators. Slight differences were found, indicating modelling limitations. Therefore, a data-driven technique for the estimation of processes with a final state that contains a large number of jets is proposed. This procedure can predict jet multiplicities up to a precision of 25% in energetic multi-jet events.
Highlights
Several beyond the standard model (BSM) models, e.g Micro-Black-Holes [1,2,3,4], R-Parity Violation (RPV) Supersymmetry [5,6] or Sphaleron induced processes [7,8] predict the possible production at the LHC of events with a large number of outcoming high energy partons
These events will give rise to final states consisting of a high multiplicity of jets, produced above the TeV scale, namely, energetic multi-jet events
The simplest approach is to couple the Leading Order (LO) calculations that give rise to two outcoming partons with a Parton Shower (PS) algorithm that can produce additional jets. While such an approach provides precise physical modelling of di-jet with soft-collinear parton emissions, it is less accurate pertaining to topologies with more than two well separated partons
Summary
Several beyond the standard model (BSM) models, e.g Micro-Black-Holes (mBH) [1,2,3,4], R-Parity Violation (RPV) Supersymmetry [5,6] or Sphaleron induced processes [7,8] predict the possible production at the LHC of events with a large number of outcoming high energy partons. These events will give rise to final states consisting of a high multiplicity of jets, produced above the TeV scale, namely, energetic multi-jet events
