- Summary note:
- Leptonic decay modes of the W boson have been well-explored in data from the
LHC. However, W hadronic decay modes are thought to make up over two thirds of all
W decays, but are avoided because of the difficulty of W reconstruction through these
channels. This thesis attempts to reconstruct W bosons through the J/\(\Psi\) + D\(_s\) decay
mode, a channel more likely to produce results compared to other hadronic modes.
This decay mode has never been experimentally explored. By making a series of cuts
on a data set taken at the Compact Muon Solenoid (CMS), and then maximizing the
signal-to-noise ratio of the reconstruction through analysis on Monte Carlo generated
data, we arrive at a point where an experimental limit can be placed on the branching
coefficient for this decay mode.
