7 TeV & 13 TeV Kaons Production Hijing Simulation at 40000 & 600 Events Jet 0,1,2 | Physicist Hammad

This video explores kaon (K⁺/K⁻) production in proton–proton collisions at two different center-of-mass energies, 7 TeV and 13 TeV, using the HIJING event generator. A total of 40,000 events were simulated at 7 TeV and 600 events at 13 TeV, with detailed analysis across different jet multiplicity classes (Jet 0, Jet 1, Jet 2). The study focuses on how kaon yields, transverse momentum (pT) spectra, and pseudorapidity (η) distributions vary with collision energy and jet activity, providing insight into the transition from soft to hard QCD processes at high energies.

The simulation workflow involves event generation, selection of charged kaons, and categorization by jet classes. By comparing Jet 0 (no reconstructed jets), Jet 1 (one jet), and Jet 2 (two or more jets), the analysis highlights differences in kaon spectra and multiplicity across energies. The video demonstrates the methodology of handling large-scale simulations at 7 TeV, as well as the challenges and statistical considerations with smaller datasets like the 600-event sample at 13 TeV.

Finally, the results show clear trends in pT hardening with jet multiplicity and provide comparative insights between 7 TeV and 13 TeV collisions. The discussion connects these findings with broader physics goals such as understanding hadronization, jet fragmentation, and kaon production mechanisms in small systems. This video is part of the Physicist Hammad series, aimed at delivering professional, research-oriented physics content for students, researchers, and enthusiasts.
