We will reach this hitherto inaccessible regime physics analysing electron-photon photon-photon interactions in extreme environment provided intense focus. The background its relevance are...
The Compact Linear Collider (CLIC) is a TeV-scale high-luminosity linear $e^+e^-$ collider under development at CERN. Following the CLIC conceptual design published in 2012, this report provides an overview of project, its current status, and future developments. It presents physics potential reports on design, technology, implementation aspects accelerator detector. foreseen to be built operated stages, centre-of-mass energies 380 GeV, 1.5 TeV 3 TeV, respectively. uses two-beam acceleration...

The further implications for search physics beyond Standard Model are also discussed.
This report summarizes the work of Energy Frontier Top Quark working group 2013 Community Summer Study (Snowmass).
Precision physics at future colliders requires highly granular calorimeters to support the Particle Flow Approach for event reconstruction. This article presents a review of about 10 - 15 years R\&D, mainly conducted within CALICE collaboration, this novel type detector. The performance large scale prototypes in beam tests validate technical concept particle flow calorimeters. comparison test data with simulation, e.g.\ hadronic showers, supports full detector studies and gives deeper...
In view of the very precise measurements on fermion couplings which will be performed at ILC250 with polarized beams, there is emerging evidence that LEP1/SLC these are an order magnitude too imprecise to match accuracies reachable ILC250. This therefore severely limit indirect sensitivity new resonances and require revisiting possibility run ILC Z pole electrons. work was done as a contribution ESU 2018-2020.
Abstract The CALICE collaboration is developing highly granular electromagnetic and hadronic calorimeters for detectors at future energy frontier electron-positron colliders. After successful tests of a physics prototype, technological prototype the Analog Hadron Calorimeter has been built, based on design construction techniques scalable to collider detector. consists steel absorber structure active layers small scintillator tiles that are individually read out by directly coupled SiPMs....
An experiment (E166) at the Stanford Linear Accelerator Center has demonstrated a scheme in which multi-GeV electron beam passed through helical undulator to generate multi-MeV, circularly polarized photons were then converted thin target produce positrons (and electrons) with longitudinal polarization above 80% 6 MeV. The results are agreement Geant4 simulations that include dominant polarization-dependent interactions of electrons, positrons, and matter.Received 8 March...
Top quark production in the process $e^+e^- \rightarrow t\bar{t}$ at a future linear electron positron collider with polarised beams is powerful tool to determine indirectly scale of new physics. The presented study, based on detailed simulation ILD detector concept, assumes centre-of-mass energy $\roots=500$\,GeV and luminosity $\mathcal{L}=500\,\invfb$ equality shared between incoming beam polarisations $P_{e^{-,+}} =\pm0.8,\mp0.3$. Events are selected which top pair decays...

This paper describes an analysis performed at 250 GeV centre of mass energy for the reaction e+e- -> bbbar with International Linear Collider, ILC, assuming integrated luminosity 500 fb-1. measurement requires determining b quark charge, which can be optimally using precise micro-vertex detector ILD and charged kaon identification provided by dE/dx information its TPC. Given that forward backward asymmetry is maximal e-L (Left-handed electron polarisation), it has been necessary to...
The high granularity of the CALICE Semi-Digital Hadronic CALorimeter (SDHCAL) provides capability to reveal track segments present in hadronic showers. These are then used as a tool probe behaviour active layers situ, better reconstruct energy these showers and also distinguish them from electromagnetic ones. In addition, comparison data simulation helps discriminate among different shower models simulation. To extract recorded SDHCAL, Hough Transform is after being adapted presence dense...
