CMS

A recent observation of an extremely rare subatomic process allows scientists to test the Standard Model’s boundaries.

Scientists working on experiments at the LHC are continually refining our understanding of the fundamental constituents of our universe. Every measurement, every new, uncovered facet of a subatomic particle comes only after a thorough and rigorous analysis of the data. The way they access that data may soon get an upgrade at Fermilab, where CMS collaborators recently installed a new solid-state technology at its computing facility. The technology will complement the standard spinning-disk hard drives that have been the dominant computer storage devices for the last several decades.

Fermilab scientists have implemented a cloud-based machine learning framework to handle data from the CMS experiment at the Large Hadron Collider. Now they can begin to use graph neural networks to boost their pattern recognition abilities in the search for new particles.

From CERN Courier, Sept. 9, 2020: The first ICHEP meeting since the publication of the update of the European strategy for particle physics covered Higgs and neutrino physics, including results from the CMS collider experiment and the DUNE, NOvA and MicroBooNE neutrino experiments.

Scientists on experiments at the LHC are redesigning their methods and building supplemental detectors to look for new particles that might be evading them.

Scientists know the Higgs boson interacts with extremely massive particles. Now, they’re starting to study how it interacts with lighter particles as well.

The ATLAS and CMS experiments at CERN have announced new results that show that the Higgs boson decays into two muons. US CMS — the United States contingent of the global CMS collaboration — played a crucial role in this result, contributing to the excellent performance of CMS detector.

What does it take to publish a scientific analysis in one of the world’s largest experiments? A huge amount of meticulous work and scrutiny goes into each paper published by CMS, a collaboration of about 3,000 scientists.

On June 19, scientists at the CMS experiment at CERN’s Large Hadron Collider published their 1,000th paper. The monumental achievement reflects an incomparable contribution to humanity’s understanding of the universe — and it’s just the beginning.

What if you want to capture an image of a process so fast that it looks blurry if the shutter is open for even a billionth of a second? This is the type of challenge scientists on experiments like CMS and ATLAS face as they study particle collisions at CERN’s Large Hadron Collider. An extremely fast new detector inside the CMS detector will allow physicists to get a sharper image of particle collisions.
