B-tagged jets are a key component in particle physics research, particularly in the study of the properties and interactions of the Higgs boson through the detection of bottom quarks. B-tagging refers to the process of identifying jets produced by the hadronization of bottom quarks, typically achieved through the detection of displaced secondary vertices within the jet, which are characteristic of B hadron decays. B-tagged jets play a crucial role in experimental analyses, serving as a valuable tool for discriminating signal processes from background events and enhancing the sensitivity of various analyses, such as searches for new particles or measurements of particle properties. Advanced techniques and algorithms are continuously developed to improve the efficiency and precision of b-tagging in high-energy physics experiments.
