TWOCRYST and ALADDIN Workshop (2024)

ALADDIN,  An Lhc Apparatus for Direct Dipole moments INvestigation, is an innovative fixed-target experiment proposed for the Large Hadron Collider (LHC) at CERN (Geneva, Switzerland) aiming for uncharted studies of charm baryon magnetic and electric dipole moments. The new experiment relies on a novel storage-ring layout capable of deflecting protons from the LHC beam halo towards a solid target paired to a bent crystal where forward-boosted charm baryons are produced and channeled inducing large electromagnetic fields and spin precession. A proof-of-principle test at the LHC, TWOCRYST, is currently under construction to demonstrate the feasibility of the proposed experiment in 2025.

3rd Workshop on electromagnetic dipole moments of unstable particles (2023)

The scope of the workshop is to stimulate a constructive scientific discussion on electromagnetic dipole measurements of unstable particles proposed for the LHC. In particular for charm and strange baryons and tau leptons.  The theoretical, experimental and machine aspects of the proposal will be reviewed and critically discussed in preparation of a future experiment at the CERN LHC. The meeting will touch few main topics:

  • electric and magnetic dipole moments of baryons and leptons;
  • channeling and spin precession in bent crystals;
  • a new fixed-target experiment at the LHC with bent crystals;
  • spin precession in the LHCb magnet;
  • experimental techniques for reconstruction of long-lived particles.

Running a flavour experiment at the LHC (2022)

Abstract: The LHCb experiment took data during the Run 1 and 2 of the LHC, between 2011 and 2018
and recorded more than 9 fb-1 of data that are used to perform measurements mainly for
heavy flavour physics. I will explain what challenges were met during data taking, 
how they were addressed to be able to run in the end with higher instantaneous
luminosity than the one for which the experiment was designed. The efficiency and stability
of the data taking were also  improved over the years in order to obtain the high quality data
sample available now.
