ALICE group at IPHC


The research group is currently working within the general physics programme of the ALICE experiment at the Large Hadron Collider (LHC) at CERN. The experiment aims at studying and characterising the hot and dense deconfined state of nuclear matter called Quark Gluon Plasma (See ALICE public page).

  • Analysis wise, our focus is given to the strange and charm flavours for various colliding systems (proton-proton, proton-lead and lead-lead) at TeV-scale energies.
  • On some more technical aspects, the group is involved in i) the development of reconstruction algorithms and ii) in the successive upgrades of the Inner Tracking System (ITS-2 (>2021), ITS-3 (>2026)) of ALICE, based on silicon pixel CMOS technology.

    (See also microtechnics, microelectronics, PICSEL groups and the C4PI platform.)

Partnerships for ALICE Inner Tracker System (LHC runs III + IV)

Detector 2 outer layers of the upgraded Inner Tracking System (ITS-2) for LHC run III (about 2021-24) of the ALICE detector
Partners Module assembly : CERN, INFN (Bari), STFC (Daresbury), ...
Stave assembly : NIKHEF (Utrecht), INFN (Torino)


The group has built some expertise based on its experience inside the ALICE Collaboration and its former participation (until 2008) in the STAR Collaboration at the Relativistic Heavy Ion Collider (RHIC) at BNL.

The group was engaged in R&D and construction of Si-strip detectors for STAR and ALICE.
