Embarking on an ambitious endeavor, Ghosh found himself amid a vast network of 3,500 physicists within ATLAS, each appearing to possess a deep understanding of the intricate workings. As a graduate student entering this realm, he was tasked with unraveling the intricate sequence of events that transpire when two protons collide. This collision gives rise to W bosons, associated with the weak nuclear force, which subsequently combine to form a Higgs boson, setting off a series of reactions. The Higgs boson then disintegrates into two Z bosons, further breaking down into leptons, such as electrons, and their corresponding anti-particles.
Ghosh’s objective was to scrutinize this process, delving into the behavior of the Higgs boson. By pinpointing the precise decay time of the Higgs boson, the potential to uncover interactions with undiscovered heavy particles loomed on the horizon, beyond the reach of the LHC’s capabilities.
- In 2017, David Rousseau of IJCLab in Orsay threw down the gauntlet to his student, Aishik Ghosh, challenging them to elevate their pursuit by identifying a distinct combination of particles. This unique amalgamation serves as a crucial piece in unlocking the mysteries of the Higgs boson
- the cornerstone of mass for other particles, unveiled in 2012.
Thus, Ghosh embarked on a mission to innovate the team’s strategies, only to stumble upon a profound realization. The assignment to isolate this specific pathway appeared incongruous, prompting a shift in perspective. At the LHC, diverse particle collisions yield a myriad of outcomes for analysis, offering a glimpse into the intricacies of the subatomic world.
