A Very High Momentum Particle Identification Detector

Understand

The construction of a new detector is proposed to extend the capabilities of ALICE in the high transverse momentum (pT) region.

• This Very High Momentum Particle Identification Detector (VHMPID) performs charged hadron identification on a track-by-track basis in the 5 GeV/c < p < 25 GeV/c momentum range and provides ALICE with new opportunities to study parton-medium interactions at LHC energies.
• The VHMPID covers up to 30% of the ALICE central barrel and presents sufficient acceptance for triggered- and tagged-jet studies, allowing for the first time identified charged hadron measurements in jets.
• This Letter of Intent summarizes the physics motivations for such a detector as well as its layout and integration into ALICE.
