The focus of our current analysis centers on constraining the mass of the excited bottom quark, denoted as b*. to achieve this, we initiate out investigation by dissecting a subset of high-mass dijet events, segregating them into control and signal regions. This segregation is accomplished by applying stringent selection criteria to fundamental jet properties such as reconstructed jet transverse momentum(pT), pseudorapidity (eta), azimuthal angle (phi), as well as variables like delta eta, delta phi, and dijet mass.
In our pursuit of precise analysis, understanding the background statistics with minimal uncertainty is paramount. To his end, we have diligently generated a dataset of 100 million dijet events using the positive weight hardest emission generator (POWHEG). This tool plays a pivotal role in augmenting our statistical precision.
