Title:
The CLIC detector: From the conceptual design and requirements to the silicon pixel detector R&D activities

The proposed Compact Linear Collider (CLIC) will provide electron-positron collisions with centre-of-mass energy operation in three stages from a few hundred GeV up to 3 TeV. This offers a rich precision physics program combined with high sensitivity to a wide range of possible new phenomena. The precision required for such measurements and the specific conditions imposed by the beam bunch sizes and time structure put strict requirements on the detector design and technology development. This includes low-mass vertexing and tracking systems with small pixels, highly granular imaging calorimeters, and a precise hit-timing resolution for all subsystems.

A variety of detector optimisation studies have been carried out to establish the overall detector performance and to assess the impact of different technology options. In parallel, ambitious technology R&D programs are pursued, addressing the challenging CLIC detector requirements and exploiting synergies with other detector R&D projects. Several software and hardware tools have been developed as part of the R&D programme, enabling efficient simulation and testing of various technology demonstrators.

This contribution introduces the CLIC experimental conditions and detector requirements and presents the optimised CLICdet detector concept, followed by examples of the ongoing R&D activities for silicon pixel detectors.

Title: The Compact Linear Collider: physics potential

The Compact Linear Collider (CLIC) is a proposed TeV-scale linear electron-positron collider based on a novel two-beam acceleration technique. With its high luminosity and a broad energy range, from 380 GeV to 3 TeV, CLIC presents a mature option for a future Higgs factory and discovery machine. Detailed studies of the CLIC physics potential based on a dedicated detector concept, CLICdet, profit from a comprehensive suite of software tools designed for physics analysis. This talk presents a general introduction to CLIC. Highlights of the CLIC physics studies will be reported, many of which rely on full simulation.

The clean environment at CLIC, its high collision energies and electron beam polarisation enable unprecedented precision in Higgs, electroweak and top quark studies. These measurements include Higgs self-coupling determination, constraining its invisible decays, studies of CP violation effects, and top-threshold scan. At high energy stages, CLIC offers promising prospects for Beyond the Standard Model physics searches. It provides both indirect sensitivity through the Effective Field Theory framework, probing extremely high new physics scales, and direct searches encompassing high-mass particles and diverse non-standard signatures. The presented studies show that CLIC surpasses the HL-LHC in its potential for precision measurements and is competitive in the exploration of many new physics scenarios.
