High Energy Physics Seminars

The SM has provided a powerful description of elementary particle physics, and it can explain most experimental findings with high precision. However, it is challenged by some recent experiments and theoretical considerations such as (g − 2)µ, Gauge Hierarchy Problem, etc. The vector-like quarks (VLQs) are well motivated in many new physics models and can be a key to solving the challenges that the SM left us. While all spin-½ particles have left- and right-handed components, the weak force only interacts with the left-handed components of Standard Model particles. However, vector-like quarks would have “ambidextrous” interactions with the weak force, giving them a bit more freedom in how they decay. In my analysis, I will be looking for channels with pair produced VLQs with top like properties decaying fully hadronically using a new boosted jet reclustering technique and cut based approach.
