The discussion focuses on calculating the delivered luminosity for the CMS experiment using data from the CERN Statistics website, which reports a total delivered luminosity of 22.98 inverse femtobarns (fb-1). The user attempted to calculate this value independently, arriving at 8.16E+42, but identified a potential error in their calculations related to the use of a plus sign instead of a minus sign. The formula used for the calculation is L = (n_b * f * N_1 * N_2) / (4 * π * σ_x * σ_y * √(1 + (θ * σ_z / (2 * σ_x))²), where n_b represents the number of colliding pairs and f is the stable beam duration.
PREREQUISITESPhysicists, researchers in high-energy physics, and students studying particle collisions and luminosity calculations will benefit from this discussion.
vela said:On the third line of your calculations, the second plus sign should have been a minus sign. I'm sure that's it even though I have no idea what your calculations were. ;)
