Diffraction in hadron-hadron collisions
The RENORM model predictions of differential and integrated diffractive, total, and total-inelastic cross sections at the LHC are confirmed by recent measurements. The predictions of several other available models are discussed, highlighting their differences from RENORM, mainly arising from the way rapidity gap formation, low- and high-mass diffraction, unitarization, and hadronization are...

Diffraction in hadron-hadron collisions
The analysis of different sets of the PDFs is made in the framework of the model of t-dependence of the GPDs. On the basis of the new high energy general structure model, which takes into account the different moments of the GPDs of the hadron the quantitative descriptions of all existing experimental data from 9.8 GeV to 7 TeV, including the Coulomb range and large momentum transfers...

Diffraction in hadron-hadron collisions
We will recall the main features of an accurate phenomenological model to describe successfully near-forward elastic scattering in
a wide energy range, including ISR, SPS and Tevatron colliders. A large step in energy domain is accomplished with the LHC collider presently running, giving a unique opportunity to confront the new data with the predictions of our theoretical approach.

Diffraction in hadron-hadron collisions
Recent results on (pi pi pi)− from COMPASS from a study of the reaction
pi- p -> pi+ pi- pi- + p at 190 GeV/c.
A new state is found, at mass = 1420 GeV with JPC = 1++ and decaying to f0(980)pi− and
f0(980) pi+pi−. This state has never been seen before and never been predicted by theorists
or anticipated by experimentalists on meson spectroscopy. Because of its very small cross
section, it...

Diffraction in hadron-hadron collisions
We study the W/Z pair production from two photon exchange in pp collisions at the LHC in order to evaluate the contributions of anomalous photon-gauge-boson couplings, predicted in many Standard Model (SM) extensions. We start by reproducing the total cross section for W+ W- production and we present the lepton invariant mass distribution corresponding to the SM signal with pT (e mu) > 30 GeV....
