Events where the two leading jets are separated by a pseudorapidity interval devoid of particle activity, known as jet-gap-jet events, are studied in proton-proton collisions at √s=13 TeV. The signature is expected from hard color-singlet exchange. Each of the highest transverse momentum...

Measurements are presented of the single-diffractive dijet cross section and the diffractive cross section as a function of the proton fractional momentum loss ξ and the four-momentum transfer squared t. Both processes p p → p X and p p → X p , i.e. with the pro...

The TOTEM collaboration at the CERN LHC has measured the differential cross-section of elastic proton–proton scattering at s√=8TeV in the squared four-momentum transfer range 0.2GeV2<|t|<1.9GeV2. This interval includes the structure with a diffractive minimum (“dip”) and a secondary maximum (“bu...
