A word from the EP Deputy Department Head - March 2022

Dear Colleagues in EP, Welcome to the first edition of the EP newsletter in 2022. Let me take a few words to introduce myself – my name is Richard Hawkings, and I started as one of the two deputy department heads in January, taking over from Roger…

Testing CPT-symmetry and the Weak Equivalence Principle with Proton/Antiproton Clock Comparisons

Even though the Standard Model of Particle Physics is incredibly successful and provides extremely accurate predictions for many physical quantities and mechanisms, the model is known to be incomplete. For instance, it fails in explaining the…

New precise measurements of CP violation and mixing in beauty and charm decays at LHCb

In 1928, a young Paul Dirac wrote one of the most spectacular papers of modern physics when he successfully unified two distinct theories, quantum mechanics and special relativity. What arose from his equations was a prediction of a new form of…

MoEDAL’s Searches for Magnetic Monopoles Produced via The Schwinger Mechanism

Magnetic monopoles (MMs) are hypothetical fundamental particles that carry isolated magnetic charge that are arguably the most important particle yet to be discovered. In 1931 Dirac first showed that a  MM was compatible with quantum mechanics [1]…

Non-resonant searches open new avenues in the hunt for axion-like particles

Axion-like-particles (ALPs) are a vast family of hypothetical particles. They are among the most compelling candidates for physics beyond the Standard Model (SM), because their existence is associated to broken symmetries, which are ubiquitous in…

LHCb VELO: “One down, one to go”

As the LHC marks the start of the final countdown to Run 3, the LHCb experiment is preparing to commission its new detector. The upgrade will allow the collaboration to pursue its physics programme into the High Luminosity era. LHCb aims to fully…

64 channel picosecond time resolution instrumentation in 25 milligrams of silicon

The EP-ESE group has finalized the development of a 64 channel picosecond TDC (Time to Digital Converter) ASIC and 20 thousand pieces have been produced. One of the key challenges for future HEP experiments is the development of very high time…

Progress towards a new calorimeter concept for the upgrade of CMS

Over two years ago we wondered if a new era for calorimetry was starting [1]. Compelled by the results reported in the Technical Design Report (TDR) of the High Granularity Calorimeter (HGCAL) for the upgrade of the CMS detector in Phase-2 of the…
