 The CMS Precision Proton Spectrometer timing system performance in Run 2, future upgrades and sensor radiation hardness studies. / Bossini, Edoardo (CERN) /CMS and TOTEM Collaborations Central exclusive processes can be studied in CMS by combining the information of the central detector with the Precision Proton Spectrometer (PPS). PPS detectors, placed symmetrically at more than 200 m from the interaction point, can detect the scattered protons that survive the interaction. [...] CMS-CR-2019-294.- Geneva : CERN, 2019 - 13 p.

 The Proton Timing System of the TOTEM experiment at LHC / Bossini, Edoardo (CERN) /TOTEM Collaboration The TOTEM experiment has developed a new timing detector to be used during a special LHCrun. The new proton timing detector, based on Ultrafast Silicon Detectors, is installed in theTOTEM Roman Pots, at 220 meters from the interaction point 5 at LHC.

 The TOTEM DAQ based on the Scalable Readout System (SRS) / Quinto, Michele (INFN, Bari) ; Cafagna, Francesco S (INFN, Bari) ; Fiergolski, Adrian (Warsaw U. of Tech. (main)) ; Radicioni, Emilio (INFN, Bari) The TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement at the LHC) experiment at LHC, has been designed to measure the total proton-proton cross-section and study the elastic and diffractive scattering at the LHC energies. In order to cope with the increased machine luminosity and the higher statistic required by the extension of the TOTEM physics program, approved for the LHC’s Run Two phase, the previous VME based data acquisition system has been replaced with a new one based on the Scalable Readout System.

 Elastic and total cross-section measurements by TOTEM: Past and future / Nemes, Frigyes Janos (CERN ; Wigner RCP, Budapest) The TOTEM experiment at the LHC has measured proton-proton elastic scattering in dedicated runs at $\sqrt{s} = 7,8$ and $2.76$ TeV centre-of-mass LHC energies. The proton-proton total cross-section $\sigma_{tot}$ has been derived for each energies using a luminosity independent method.

 Measurements, status and plans of the TOTEM experiment at the LHC / Ferro, Fabrizio (INFN, Genoa) /TOTEM The TOTEM collaboration at the LHC has measured the elastic, inelastic and total proton-proton cross sections at several center of mass energies and is carrying on a rich program of measurements of diffractive physics together with the CMS collaboration. The talk will review the TOTEM measurements mainly focusing on the newest and most significant ones. [...] 2017 - 5 p. - Published in : J. Phys. : Conf.

 The TOTEM experiment at LHC for proton-proton cross section measurements / Cafagna, Francesco (INFN, Bari) /TOTEM The LHC energy begins to overlap with the energy range where extreme energy cosmic-ray showers are studied. Investigations of proton-proton interactions at the LHC are therefore of high importance for the study of the development of cosmic-ray showers in the atmosphere and thus for the measurements of the high-energy cosmic-ray spectra and composition.

 A new timing detector for the CT-PPS project / Arcidiacono, R (INFN, Turin ; Piemonte Orientale U., Novara) /CMS ; TOTEM The CT-PPS detector will be installed close to the beam line on both sides of CMS, 200 m downstream the interaction point. This detector will measure forward scattered protons, allowing detailed studies of diffractive hadron physics and Central Exclusive Production. [...] 2017 - 4 p. - Published in : Nucl. Instrum.

 Development of a timing detector for the TOTEM experiment at the LHC / Minafra, Nicola (Kansas U.) /TOTEM The upgrade program of the TOTEM experiment foresees the installation of timing detectors in- side vertical Roman Pots to allow the reconstruction of the longitudinal vertex position in presence of event pile-up in high β ∗ dedicated runs. The small available space inside the Roman Pot and the required time precision led to the study of a solution using single crystal CVD diamonds.

 Measurements of the elastic, inelastic and total $pp$ cross sections with the ATLAS, CMS and TOTEM detectors / Stark, Simon Holm (Bohr Inst.) The elastic (σel), inelastic (σinel), and total (σtot) cross sections are related through the diσerential elastic cross section using the optical theorem. ATLAS and TOTEM have used forward detectors to measure the elastic scattering at √s = 8 TeV.

 Hard diffraction and Photon-induced processes with Proton Tagging at the LHC / Royon, Christophe (Kansas U.) We describe some of the measurements that can be performed at the LHC by the TOTEM, CMS and ATLAS collaborations on hard diffraction in order to understand better the structure of the Pomeron. We will also describe the prospects concerning the search for quartic γγγγ anomalous couplings.. 2017 - 7 p. - Published in : EPJ Web Conf. 141 (2017) 03002 Fulltext: PDF; In : XLVI International Symposium on Multiparticle Dynamics, Jeju Island, Republic of Korea, 29 Aug - 2 Sep 2016, pp.03002
