In 2008, the Large Hadron Collider (LHC) -- the highest-energy particle accelerator ever built -- will come into operation at the CERN laboratory for particle physics. The main objective of the LHC is to explore the physics of fundamental particles and their interactions at unprecedented collision energies and rates. By studying the debris of proton-proton (p-p) and heavy-ions collisions at multi-TeV energies, the four main experiments at the LHC -- ALICE, ATLAS, CMS, and LHCb -- will try to provide answers to various of the most important open issues in physics today. The researcher has been playing a very active role in the development of the forward physics programme of the CMS collaboration and plans to extend this work within the LHCb experiment at the LHC. The LHCb detector -- with a single-arm configuration – has excellent and varied particle detection and identification capabilities in the forward hemisphere. Pions, kaons, electrons, photons, muons and jets can be well measured in the pseudo-rapidity range 2 < eta < 5. This project focuses on finalizing the current work of the applicant with CMS and on exploiting the LHCb forward detection capabilities to carry out measurements in various sectors of the SM (and beyond it) such as (i) Quantum Chromodynamics (parton distribution functions at low values of parton fractional momentum, via forward heavy-quarks, quarkonia, prompt photons, Drell-Yan and vector bosons), (ii) electroweak physics (via multiple gauge-boson production at forward rapidities), and tests of the feasibility for (iii) new physics measurements (Higgs boson in the b-bbar decay channel, enhanced in various supersymmetric extensions of the SM, Z-prime bosons in the dilepton channel, ...).
