 Combined Fits of CLIC Higgs Results for the Snowmass Process / Simon, F ; Szalay, M ; Roloff, P /CERN Linear Collider Detector collaboration This note presents three combined fits of CLIC Higgs physics results, a model- independent fit based on minimal assumptions and two model-dependent fits assuming that the total width is described by the sum of nine (seven) different visible final states with coupling parameters given by the deviation of the re- spective partial widths from their SM values. The input values are a snapshot of the CLIC Higgs analyses as of September 2013. [...] LCD-Note-2013-012.- Geneva : CERN, 2013 - 8. Fulltext: PDF;

 CLIC Detector Power Requirements / Gaddi, A ; Dannheim, D /CERN Linear Collider Detector collaboration An estimate for the CLIC detector power requirements is outlined starting from the available data on power consumptions of the four LHC experiments and considering the differences between a typical LHC Detector (CMS) and the CLIC baseline detector concept. In particular the impact of the power pulsing scheme for the CLIC Detector electronics on the overall detector consumption is considered. [...] LCD-Note-2013-011.- Geneva : CERN, 2013 Fulltext: PDF;

 Shower development of particles with momenta from 10 to 100 GeV in the CALICE Scintillator-Tungsten HCAL / Lucaci-Timoce, A (CERN) /CERN Linear Collider Detector collaboration (CALICE) We present a study of the showers initiated by high momentum (10 ≤ pbeam ≤ 100 GeV) electrons, pions and protons in the highly granular CALICE analogue scintillator-tungsten hadronic calorimeter. The data were taken at the CERN SPS in 2011. [...] LCD-Note-2013-002; AIDA-NOTE-2015-011.- Geneva : CERN, 2013 Fulltext: AIDA-NOTE-2015-011 - PDF; LCD-Note-2013-002 - PDF;

 CLIC inner detectors cooling simulations / Duarte Ramos, F. ; Gerwig, H. ; Villarejo Bermudez, M. /CERN Linear Collider Detector collaboration The strict requirements in terms of material budget for the inner region of the CLIC detector concepts require the use of a dry gas for the cooling of the respective sen- sors. This, in conjunction with the compactness of the inner volumes, poses several challenges for the design of a cooling system that is able to fulfil the required detec- tor specifications.

 Beam Profiling through Wire Chambing Tracking / Nash, W (CERN ; Boston U.) ; Grefe, C (CERN) /CERN Linear Collider Detector collaboration This note describes the calibration of the Delay Wire Chambers (DWCs) used during test runs of CALICE’s Tungsten Digital Hadron Calorimeter (W-DHCAL) prototype in CERN’s SPS beam line (10 – 300 GeV)..

 Measurement of the top Yukawa Coupling at a 1 TeV International Linear Collider using the SiD detector / Roloff, Philipp (CERN) ; Strube, Jan (CERN) One of the detector benchmark processes investigated for the SiD Detailed Baseline Design (DBD) is given by: $e^+ e^- \to t\bar{t}H$, where H is the Standard Model Higgs boson of mass 125 GeV.

 Differential Luminosity Measurement using Bhabha Events / Poss, Stephane ; Sailer, Andre /CERN Linear Collider Detector collaboration A good knowledge of the luminosity spectrum is mandatory for many measurements at future e+e- colliders. As the beam-parameters determining the luminosity spectrum cannot be measured precisely, the luminosity spectrum has to be measured through a gauge process with the detector.

 Measurement of sigma(ee->Hnunu)xBR(H->tautau) at CLIC @ 1.4 TeV / Münnich, A. /CERN Linear Collider Detector collaboration This detector benchmark study evaluates the statistical precision with which the H -> tautau branching ratio times cross section can be measured at CLIC running at rout(s)= 1.4 TeV. Only the hadronic decays of taus are considered.. LCD-Note-2012-010.- Geneva : CERN, 2013 Fulltext: PDF;

 Particle Identification with Cherenkov detectors in the 2011 CALICE Tungsten Analog Hadronic Calorimeter Test Beam at the CERN SPS / Dannheim, D (CERN) ; Elsener, K (CERN) ; Klempt, W (CERN) ; Lucaci Timoce, A (CERN) ; van der Kraaij, E (Bergen U.) /CERN Linear Collider Detector collaboration In 2011 the CALICE Tungsten Analog Hadronic Calorimeter prototype (W-AHCAL) was exposed to mixed beams of electrons, pions, kaons and protons with momenta from 10 to 300 GeV in the CERN SPS H8 beam line. The selection of pion, kaon and proton samples is based on the information obtained from two Cherenkov threshold counters. [...] LCD-Note-2013-006; AIDA-NOTE-2015-012.- Geneva : CERN, 2013 - 19 p.

 Occupancy in the CLIC ILD Time Projection Chamber using Pixelised Readout / Killenberg, Martin /CERN Linear Collider Detector collaboration The occupancy in the CLIC ILD TPC caused by the beam induced background from gamma gamma -> hadrons, e+e- pairs and beam halo muons is very high for conventional pad readout. We show that the occupancy for a pixelised TPC readout is moderate and might be a viable solution to operate a TPC at CLIC.. LCD-Note-2013-005.- Geneva : CERN, 2013 - 11. Fulltext: PDF;
