The CMS experiment has observed the Higgs boson in numerous fermionic and bosonic decay channels, established its spin–parity quantum numbers, determined its mass and measured its production cross-sections in various modes. Here the CMS Collaboration reports the most up-to-date combination of ...
This article summarizes the latest highlights from the CMS experiment as presented at the Lepton Photon conference 2017 in Guangzhou, China. A selection of the latest physics results, the latest detector upgrades, and the current detector status was shown. CMS has analyzed the full dataset of ...
Recent results from the CMS Experiment 来自 Semantic Scholar 喜欢 0 阅读量: 19 作者: F Costanza 摘要: With the increase in center-of-mass energy, a new energy frontier has been opened by the Large Hadron Collider. More than 25 fb$^{-1}$ of proton-proton collisions at $\sqrt{s} =$...
Several improvements have been introduced into the CMS experiment since the discovery of the Higgs boson in 2012. These include: The replacement, in late 2016, of the silicon pixel detector, with a new one comprising four concentric layers in the barrel region, at radii of 29 mm, 68 ...

The CMS experiment was also motivated to search for Y→ XX → 4-jets by a candidate event recorded in 2017, which was presented by a previous CMS search for dijet resonances (figure 1). This spectacular event has four high transverse-momentum jets, forming two dijet pairs each with an inv...
A report from the CMS experiment. Fig. 1. The tW signal (orange) increases in proportion to the tt background (red) as a function of the random forest output. These events have one jet identified as coming from a b quark. Source: CMS-PAS-TOP-23-008 Being the most massive known ...
The Run Control and Monitor System (RCMS) of the CMS experiment is the set of hardware and software components responsible for controlling and monitoring the experiment during data-taking. It provides users with a "virtual counting room", enabling them to operate the experiment and to monitor det...
