Anomaly at the Threshold: A Closer Look at tt̄ Events in CMS
Anomaly at the Threshold: A Closer Look at tt̄ Events in CMS Some of the most intriguing developments in physics begin not with a discovery, but with an anomaly, subtle, persistent, and difficult to ignore. In 2019, CMS reported a mild excess of around three standard deviations in a search for heavy pseudoscalar (A) or

ATLAS Approaching a Breakthrough in Diboson Polarization with Run-3 Data
ATLAS Approaching a Breakthrough in Diboson Polarization with Run-3 Data The study of the polarisation of vector boson scattering (VBS) processes provides a unique test of the Higgs mechanism’s role in taming high-energy electroweak interactions, making it indispensable for fundamental physics for the last decades. As the LHC enters its Run-3 phase, this study is

TELMAX: A New Era of Flexibility at CERN’s Antimatter Factory
TELMAX: A New Era of Flexibility at CERN's Antimatter Factory PAX UHV test chamber equipped with linear target manipulator and Ti x-ray window. The ADR cryostat containing the TES detector can be seen facing the chamber in its measurement position. X-rays from the antiprotonic atom cascade traverse the Ti window and are measured with the

Isolated photon measurements in Pb–Pb collisions with ALICE
Isolated photon measurements in Pb–Pb collisions with ALICE Heavy-ion collisions (AA) at ultrarelativistic energies at the RHIC and LHC have produced during the last 25 and 15 years, respectively, an extremely hot and dense environment, a strongly interacting coloured medium named “quark-gluon plasma” (QGP), a state of matter where quarks and gluons are not confined
