Could you imagine what the dark part of the universe is like?  The Standard Model of Particle Physics explains matter at the subatomic level and the related phenomena such as interactions and forces between the subatomic particles. Still, we…

The interaction of the Higgs boson with its own field leads to its mass generation. Since the Higgs boson mass has already been measured, the study of the Higgs pair production at the LHC reveals directly the strength of the Higgs self coupling λHHH…

High-energy particle accelerators are unique tools to study the structure of matter at the shortest distances. The most powerful accelerator today is the CERN Large Hadron Collider (LHC) that has so far collided beams of protons up to center-of-mass…

  For the first time, CMS physicists extract the fundamental parameters of QCD together with constraints on the New Physics.  Any tiny failure of the Standard Model to explain data behaviour is a possible window for the New Physics.…

The most powerful particle collider in the world, the Large Hadron Collider (LHC), was built in the 27 km tunnel originally excavated for the highest energy electron-positron collider ever built, LEP. As an extraordinarily sensitive machine, LEP was…

Congratulations to Andrew Gilbert, Marco Luccini and Meng Xiao for winning the CMS Young Researchers Prize for 2021! The CMS Young Researchers Prize is intended to recognise the outstanding achievements of young members of CMS. It is awarded…

The awardees of the 2020 CMS Thesis Award are Matteo Defranchis, Cristina Martin Perez and Thorben Quast! Every year, since 2000, the CMS Thesis Award Committee recognizes and rewards excellence in the CMS PhD student research. Thesis can be written…

CMS members Phil Harris and Indara Suarez have been awarded with the US Department of Energy (DOE) Early-Career Researcher Grant!  The DOE Early CareerResearch Program is designed to help the scientific workforce by providing support to…

Using the golden decay channel to understand the production of the Higgs boson The standard model of particle physics is currently the best way to describe interactions of fundamental particles that make up our Universe. It has been tested over many…

What does the decay of a bottom quark look like? Fragmentation, also known as hadronization, is when particles that contain quarks or gluons create other particles via the strong interaction. The fragmentation process cannot be exactly…

A shot in the dark: Can jets recoil against Dark Matter? In their 2020 hit single ‘A Shot in the Dark’ the rock band AC/DC got it right in many ways: “A shot in the dark  Make you feel alright  A shot in the dark  All through the…

Using machine learning to improve the detection of new physics in the interactions of the top quark   Although our theory describing the interactions between fundamental particles is exceptionally successful, it has weaknesses. You may have…
