 Measurement setup at light source operational: Milestone M4.3 / Perez, Francis (ALBA) ; Chiggiato, Paolo (CERN) The design of the experimental setup for the measurements of the FCC-hh beam screen prototype to be installed at the ANKA lightsource has been completed and the alignment strategy and procedure has been validated by the CERN and KIT teams. In this report, a complete description of the setup and the program of measurements under different operation conditions is presented.. CERN-ACC-2016-0110.- Geneva : CERN, 2016 Fulltext: PDF;

 Probing Anomalous WW γ and WWZ Couplings with Polarized Electron Beam at the LHeC and FCC-Ep Collider / Turk Cakir, I ((Istanbul Aydin University)) ; Senol, A (Kastamonu University) ; Tasci, A T (Kastamonu University) ; Cakir, O (Istanbul Aydin University) We study the anomalous WWγ and WWZ couplings by calculating total cross sections of two processes at the LHeC with electron beam energy Ee=140 GeV and the proton beam energy Ep=7 TeV, and at the FCC-ep collider with the polarized electron beam energy Ee=80 GeV and the proton beam energy Ep=50 TeV. At the LHeC with electron beam polarization, we obtain the results for the difference of upper and lower bounds as (0.975, 0.118) and (0.285, 0.009) for the anomalous (∆κγ, λγ) and (∆κz, λz) couplings, respectively.

 Probing charged Higgs boson couplings at a future circular hadron collider / Turk Cakir, I (Istanbul Aydin University) ; Kuday, S (Istanbul Aydin University) ; Saygin, H (Istanbul Aydin University) ; Senol, A (Abant Izzet Baysal University) ; Cakir, O (Ankara University) Many of the new physics models predict a light Higgs boson similar to the Higgs boson of the Standard Model (SM) and also extra scalar bosons. Beyond the search channels for a SM Higgs boson, the future collider experiments will explore additional channels that are specific to extended Higgs sectors [...] Geneva : CERN, 2016 - Published in : : 94 (2016) , no. 1 Access to fulltext document: PDF;
