Description
on the behalf of the ALICE‐FoCal Collaboration
Direct photon production at forward rapidity is a promising probe for the gluon content of protons and nuclei at small *x*.
In particular, the measurement of the nuclear modification factor for direct photons in
p–A collisions at the LHC is a crucial test for gluon saturation.
A new forward calorimeter (FoCal) is proposed as an upgrade to the ALICE experiment.
The detector will cover the range 3.5 < η < 5 which probes the gluon distributions at *x* ~ 10‐5 and Q ~ *p*T > 4 GeV. Performance studies show that an extremely high‐granularity calorimeter is required. Results from R&D for this project will be discussed.
