Description

The new planned QCD facility at the M2 beam line of the CERN
SPS, will be a successor of COMPASS, and will have a broad
experimental programme addressing fundamental issues
leading to significant improvements in our understanding
of strong interactions. After a brief summary of the planned
research in hadron partonic structure and hadron spectroscopy,
the presentation will focus on two items of the programme,
foreseen after CERN accelerator long shutdown 3:
the spectroscopy and the gluon content of kaons
(the latter via prompt-photon production) and low energy
tests of QCD employing the Primakoff reactions
or the first ever measurements of the kaon polarisability.
A unique tool for these measurements is a high-energy,
high-intensity radio-frequency separated hadron beams
which could be made possible by a major upgrade of the
M2 beam line.

An experimental backbone of the new facility will be the
upgraded multi-purpose two-stage magnetic spectrometer
of COMPASS in the experimental hall EHN2. Individual
instrumentation with modern detector architecture
will be constructed and installed in that hall.
