Talk:Event (particle physics)

definition of Event

I think of an "event" as one interaction, not one spill of data (one bunch crossing). The article implies that each bunch crossing at LHC will be one event, with many interactions. I would have thought that each bunch crossing at LHC contains many events. Thoughts? Josh Thompson 05:07, 8 February 2007 (UTC)[reply]

   Thats what I would think based on the difinition given for Event (relativity). Maybe this is why they are given separate articles. Drxenocide (talk) 17:18, 16 February 2011 (UTC)[reply]

Collision, decay, … what else?

Would it be correct to say that all known events can be classified to collisions (including elastic and inelastic ones) and decays? Incnis Mrsi (talk) 05:28, 5 June 2013 (UTC)[reply]

Dubious

"Physical quantities used to analyze events include the differential cross section, the flux of the beams (which in turn depends on the number density of the particles in the beam and their average velocity), and the rate and luminosity of the experiment."

For a start, you don't use any of these quantities to analyse a single event. Flux and luminosity are highly correlated, so why mention both? Cross sections are calculated from rates and luminosities, which are in turn measured from counting events. But first you need to do something (i.e. analyse) the events in order to know which ones to count. Quantities used to analyse events are things like transverse momentum, invariant mass, helicity angles, flight distance, etc. Dukwon (talk) 22:26, 13 February 2017 (UTC)[reply]
