요약	Missing transverse energy (MET) is a powerful technique used in high-energy physics to infer the presence of invisible particles, primarily neutrinos, that escape a detector without leaving a trace. By measuring the imbalance of transverse momentum in the event, physicists can detect signatures of weakly interacting particles crucial for studying the Standard Model and searching for new physics beyond it.	The anti-kT jet algorithm, introduced by Cacciari and Salam in 2008, is a sequential recombination jet clustering algorithm widely used in high-energy physics to group final-state particles into jets. Unlike earlier algorithms, anti-kT produces jets with regular cone-like geometries in transverse momentum-rapidity space, making it ideal for precision measurements and new physics searches.
