150. The results of the TOTEM experiment

Diffraction in hadron-hadron collisions (experiment)

The TOTEM experiment at the LHC has measured proton-proton elastic scattering in dedicated runs at \sqrt{s}=7 and 8 TeV centre-of-mass LHC energies. The proton-proton total cross-section \sigma_{tot} has been derived for both energies using a luminosity independent method. TOTEM has excluded a purely exponential differential cross-section for elastic proton-proton scattering with significance...

Diffraction in hadron-hadron collisions (experiment)

The total pp cross section is a fundamental property of the strong interaction which can not be calculated in perturbative QCD but only described based on phenomenological models. The ATLAS collaboration has recently measured the total inelastic protonproton cross section and the diffractive part of the inelastic cross section at 13 TeV in special data sets taken with low beam currents...

160. CMS results on soft and hard diffraction

Diffraction in hadron-hadron collisions (experiment)

The measurement of the soft diffractive cross sections in single- and double-diffractive final states is presented at 7 TeV. Furthermore, also the production of jet-gap-get final states is discussed and the results are interpreted in terms of a hard color singlet exchange. Finally, general features of particle production also in single-diffractive enhanced events are shown at 13TeV.

105. Measurements of identified particle spectra in diffractive $pp$ collisions with the STAR detector at RHIC

Diffraction in hadron-hadron collisions (experiment)

We present the diffractive program with the STAR Roman Pot detectors at RHIC, focusing on the spectra of identified charged particles as pions, kaons and protons and their anti-particle counterparts in Single Diffraction $(p+p\to p+X)$ and Central Diffraction $(p+p\to p+X+p)$ processes. The final state proton(s) were tagged in the STAR Roman Pot system while the identified charged particle...

166. Hadronic Interaction Model Calibration with LHCf data at LHC

Diffraction in hadron-hadron collisions (experiment)

The LHCf experiment is aimed to provide precise measurements of the spectra of neutral particles produced in the very forward region at LHC. These measurements provide a calibration tool to tune the hadronic interaction models used by groundbased cosmic rays experiments up to the highest energy currently available at accelerator facilities and are hence of fundamental importance to...
