In the last week and a half, a lot of computing activity took place for the PPC. We were heavily involved in the Computing Operations Workshop (March 12-13, 2026), the Computing and Offline Week (March 16-20, 2026), and, right in…
A muon, the heavier counterpart of the electron, serves as one of the clearest signatures of various unique and interesting processes at the Large Hadron Collider (LHC). Due to its small interaction cross-section with ordinary matter, a muon can pass…
In 2024, CMS collected around 50 PB of raw data and generated more than 75 PB of simulated data. Together with prompt processing, this amounts to more than 150 PB of new data. Using such an enormous amount of data…
In 2017, the Large Hadron Collider (LHC) achieved a groundbreaking milestone in instantaneous luminosity, delivering data at twice the rate it was originally designed for. This presented a new challenge for the CMS detector: efficiently selecting and retaining significant events…
At the end of March (18-22), CMS held a major internal workshop (Computing and Offline Week) dedicated to issues related to data processing, distribution, and analysis. This workshop occurs twice a year and brings together experts from various laboratories, computing…
Run 2 results attracted significant interest in heavy flavor physics at the LHC. The highlights of these findings include a 3-sigma discrepancy in the decay rate of the B meson into charm mesons with either a muon or a tau,…
Some people seem to be puzzled by the update of the R(K) and R(K*) measurements presented today by the LHCb collaboration. Renato Quagliani made a great presentation explaining it all, but in case you missed it, I asked ChatGPT for…
