Title: Lessons from LHC elastic and diffractive data

In the light of LHC data, we discuss the global description of all high-energy elastic and diffractive data, using a one-pomeron model, but including multi-pomeron interactions. The LHC data indicate the need of a k{sub t}(s) behaviour, where k{sub t} is the gluon transverse momentum along the partonic ladder structure which describes the pomeron. We also discuss tensions in the data, as well as the t dependence of the slope of dσ{sub el}/dt in the small t domain.
