❓Can four leptons emerge from a single Z boson? The CMS experiment at CERN searches for rare transformations of the Z boson into two muons and two taus to investigate whether muons and taus behave in the same way or differently. Read the full CMS briefing here: https://lnkd.in/gSDJVA53
À propos
The CMS experiment is one of the big detector at the largest particle physics accelerator in the world, the Large Hadron Collider(LHC) at CERN. More than 5000 physicists, engineers, computer scientists, technicians, administrative personnel, and students from over 50 countries across the globe work together to advance scientific knowledge, making CMS one of the largest scientific collaborations in the world. Founded in 1992, CMS is one of the two experiments at the #LHC that announced the discovery of the Higgs boson in 2012, opening a new chapter in particle physics. The CMS detector acts as a giant high-speed camera, taking “3D photographs” of the subatomic particles’ collisions, leading to a better understanding of the structure of matter and of the forces that rule the universe at the sub-atomic scale.

CMS Collaboration a republié ceci
It’s #Paris2024 🇫🇷! To celebrate we’ll be looking at 5 #Olympics themed particle physics stories. First up we're visiting the iconic Eiffel Tower, which served as Theodor Wulf's laboratory in 1909 for his cosmic ray experiment. In the early 1900s, scientists were trying to find the source of the mysterious radiation being picked up by their electroscopes - early scientific instruments that detected electric charge. At the time, they thought all the radiation came from the Earth's rocks. Wulf decided to test this idea in 1909 by bringing an electroscope up the Eiffel Tower. He measured more ionising radiation than would be expected if the ground was the only source of radiation. Further experiments by Hess and Steinke showed that the extra unexpected radiation was due to cosmic rays! These are high energy particles that travel through space at almost the speed of light before hitting our atmosphere, where some go on to reach the Earth's surface.

Congratulations to CMS physicist Dr Jennifer Ngadiuba, who has won the IUPAP C11 Early Career Award 2024. This prestigious award honours two early career scientists for their excellence in the field of Particles and Fields during the biannual #ICHEP conference. The award recognises Dr Ngadiuba’s achievements in "co-design, development and deployment of novel machine learning techniques to address complex elementary particle physics challenges with a focus on ultra-fast real-time data analysis on hardware triggers and for model agnostic searches for beyond the Standard Model physics signals at the Large Hadron Collider".

Meet the heavyweight champions of the world of fundamental forces: the W and Z bosons! But how often are they produced in #LHC collisions? The CMS Collaboration at CERN presents an in-depth study on their production at the staggering energy of 13.6 TeV.

A new, innovative approach means that CMS can now reduce the need for computing resources! Currently, simulations put enormous pressure on existing hardware - like trying to run a brand-new game on an old console. In this study, CMS harnesses #machinelearning to simulate new models in the background without a performance penalty, allowing the existing resources to stretch even further.

The case of the quantum optician! At ICHEP 2024, CMS presents an exciting observable that has never been measured in heavy-ion collisions before: how jets produced during these highly-energetic collisions are affected when within sight of quark-gluon plasma.
