Abstract

A minimal extension of the standard model giving rise to baryogenesis is studied. This model includes the interaction of heavy color-triplet scalars (∼TeV) with a light Majorana fermion (∼GeV) which is a potential non-thermal dark matter (DM) candidate and an up-type quark. The color-triplet scalars would be produced via fusion of two down-type quarks (d and d). We investigate this process with d, s and b quarks. This model yields events with a modified monojet signature, where a light jet with high transverse momentum is opposed by large missing transverse energy and a soft b-quark jet. Detailed simulation studies will be presented to study the interactions of such massive scalars by optimizing a Boosted Decision Tree (BDT) on this type of events.
