INFN Working Group

High Intensity Frontier (HIF)

On November 2003, “Gruppo I” , the INFN Scientific Committee scrutinizing HEP experiments at accelerators, set up a Working Group

to study Physics opportunities offered by: new high intensity hadron beams,

resulting either by upgrades of the present ones either by new machines

The aim of this Working Group is: • to contribute to the Villar Meeting on Autumn

• to submit specific recommendations to INFN before the end

of this year

The study is conducted inside the framework of the present

accelerators complex at CERN, taking into account:

• improvements of the existing facilities

• the construction of new machines

Inescapable request:

Upgrades or new machines must represent a real opportunityto improve the LHC luminosity.

LHC represents the absolute priority for INFN

HIPSHIPS

The workshop deals with medium and long term opportunities for particle and nuclear physics, offered by high intensity proton sources.

Discussions will focus on particle and accelerator physics to investigate new High Intensity Frontiers.

Many areas can benefit from high current beams: • experiments with kaons and muons

(CP violation, Lepton Flavour violation, g-2 and muon EDM measurements) • neutrino beams (superbeams, beta-beams and factories)• hadron studies (spectroscopy, DIS, structure functions, antiprotons)• nuclear physics

Present projects for new accelerators will be reported and promising ideas for future proposals will be brought forward.
