In this paper we discuss the Odderon contribution in our model[19] that gives a fairly good description of $\sigma_{\rm tot}$ $\sigma_{\rm el}$and $B_{\rm el}$ for proton-proton scattering. We show that the shadowing corrections are large,…

We present some physics topics that can be studied at the LHC using proton tagging. We distinguish the QCD (Pomeron structure, BFKL analysis...) from the exploratory physics topics (HIggs boson, anomalous couplings between photons and $W/Z$…
