The prestigious Breakthrough Prize in Fundamental Physics has been awarded to the four major experiments at CERN’s Large Hadron Collider: ATLAS, ALICE, CMS, and LHCb. Often referred to as the “Oscars of Science”, the $3 million award honors groundbreaking achievements in particle physics. It was awarded for “detailed measurements of ...

On Wednesday and Thursday, the HEP group hosted the first TrackOpt workshop at the Untere Schloss in Siegen, bringing together researchers to discuss tracking challenges in particle physics, microfluidics, and microscopy. The event included an introduction to the working principles of the ATLAS detector and lab tours at the Emmy ...

Physicists from the University of Siegen are actively working on upgrading the ATLAS detector for the High Luminosity phase of the Large Hadron Collider, scheduled to begin in 2030. Recently, a delegation from Siegen, including the university's rector and prorector for research, infrastructure, and networking, visited CERN and got to ...

For nearly 20 years, physicists from the University of Siegen have been working on researching cosmic radiation at the Pierre Auger Observatory in Argentina. The international collaborative project has now been extended to 2035, with a formal agreement signed during a special ceremony. Representing the University of Siegen at the ...

We are happy to announce that our new group member Dr. Elisabeth Schopf has been elected as the next ATLAS-Germany Higgs convenor for a three-year term.

The Experimental Particle Physics Group has received continued funding from the Federal Ministry of Education and Research (BMBF) for its involvement in the ATLAS experiment.

Markus will try to motivate very young students to study physics in some years. He will deliver a talk about CERN, the smallest particles and its connection to the Big Bang, today starting at 5pm at Campus Unteres Schloss. About 200 interested kids aged 8-12 are expected to join. Read ...

A paper of the Pierre Auger Collaboration about the search for photons with energies above $2\times10^{17} \, \text{eV}$, with major contributions from the Siegen Auger group, was recently published in The Astrophysical Journal. The now published results represent the strictest upper bounds on the integral flux of photons in the ...
