Understand perfectly inelastic collisions through a simple clay ball example. This video explains how momentum is conserved while kinetic energy is not, helping you visualize what happens when objects ...

where N is the number of selected events, N BG is the number of background events, f ξ < 5 × 10-6 is the fraction of events that pass the event selection but have ξ<5×10 −6, is the integrated ...
