Something Curious at the Large Hadron Collider

From the CMS talk at Berkeley; I’ve added the red dots and excised the low-statistics four-lepton results. Table of numbers of events at CMS in various categories. MET is a measure of whether invisible particles are present; HT is a measure of how much energy is in visible particles. No-OSSF means that if there is an electron there is no positron; if there is a muon there is no antimuon; etc. No Z means there are no lepton-antilepton pairs that came from a Z-particle’s decay; if there is no-OSSF there cannot be a Z, so that isn’t marked. “obs” means number of events observed, SM expectation means the prediction of the equations of the Standard Model of particle physics (supplemented with any detector-related effects that must be modeled carefully.) N(tau) means the number of taus and anti-taus observed in the event. A few entries where observation somewhat exceeds expectation are marked (by me) with red dots……
