Diffraction in hadron-hadron collisions (phenomenology/theory)
Precision predictions of soft and hard diffraction, elastic scattering, and total proton-proton cross sections, based on a tensor-Pomeron implementation of the RENORM model, are compared to the latest experimental results at the LHC and cosmic-ray experiments, and extended to the planned SuperCollider energies.

Diffraction in hadron-hadron collisions (phenomenology/theory)
We present estimates of the cross sections and differential distributions for central exclusive two and four pions production being studied at RHIC and LHC. The amplitudes for the processes are formulated in terms of the double tensor pomeron and $f_{2 \Reg}$ reggeon exchanges with the vertices respecting the standard crossing and charge-conjugation relations of Quantum Field Theory.

Diffraction in hadron-hadron collisions (phenomenology/theory)
The perturbative QCD expansion for J/psi photoproduction appears to be unstable: the NLO contribution is large (and of opposite sign) to the LO contribution. Moreover, the predictions are very sensitive to the choice of factorization and renormalization scales. Here we show that perturbative stability is achieved by imposing a `Q_0 cut' on the NLO coefficient functions; a cut which is...

Diffraction in hadron-hadron collisions (phenomenology/theory)
I present a brief overview of recent advances in single diffractive Drell-Yan, heavy flavour and Higgs boson production at forward rapidities in the dipole picture. Physical reasons for diffractive factorisation breaking in single diffractive production are discussed in detail. Angular correlation in forward diffractive heavy flavor and Drell-Yan production processes is considered as a natural...
