Looking Forward to Forward Physics

  Recently there has been much interest in studying events
with tagged forward protons at present 
and forthcoming hadronic colliders.
This would allow not only to monitor the luminosity of the
colliding protons with high accuracy but also can provide the new
ways to investigate the subtle issues of QCD  and to
search for the manifestations of New Physics. 

 We discuss the central exclusive diffractive production (CEDP) 
of various heavy systems (e.g. Higgs, dijets, SUSY particles )
at the LHC and Tevatron energies. We quantify the rates
and the signal-to-background ratios
for these processes. 
 
 The main emphasis is on Higgs production.
 Special attention is paid to the studies in the regions in the MSSM
 parameter space where the CEDP is found to have unique advantages
 as compared to the traditional non-diffractive strategies.
 
 
 We show that the physics programme
 with the tagged forward protons is in many aspects complementary
to both, the standard approaches at hadronic colliders, 
and to the studies at a future linear collider.
