In response to the 2013 Update of European Strategy for Particle Physics, Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This covers a highest-luminosity high-energy lepton collider (FCC-ee) and energy-frontier hadron (FCC-hh), which could, successively, be installed in same 100 km tunnel. The scientific capabilities integrated FCC programme would serve worldwide community throughout 21st century. also investigates LHC energy upgrade,...
We review the physics opportunities of Future Circular Collider, covering its e+e-, pp, ep and heavy ion programmes. describe measurement capabilities each FCC component, addressing study electroweak, Higgs strong interactions, top quark flavour, as well phenomena beyond Standard Model. highlight synergy complementarity different colliders, which will contribute to a uniquely coherent ambitious research programme, providing an unmatchable combination precision sensitivity new physics.

We have measured the mass of Z boson to be 91.11±0.23 GeV/c2, and its width 1.61+0.60−0.43 GeV. If we constrain visible standard-model value, find partial invisible decay modes 0.62±0.23 GeV, corresponding 3.8±1.4 neutrino species.Received 24 July 1989DOI:https://doi.org/10.1103/PhysRevLett.63.724©1989 American Physical Society
If the Standard Model explanation of CP violation is correct, then measurements CP-violating asymmetries in $B$ meson decays can principle determine entire quark mixing matrix.
A description of the design characteristics CELLO, a large 4Π magnetic detector at PETRA, is given and first results beam operation are presented.
Abstract The PICOSEC Micromegas (MM) detector is a precise timing gaseous based on MM operating in two-stage amplification mode and Cherenkov radiator. Prototypes equipped with cesium iodide (CsI) photocathodes have shown promising time resolutions as 24 picoseconds (ps) for Minimum Ionizing Particles. However, due to the high hygroscopicity susceptibility ion bombardment of CsI photocathodes, alternative photocathode materials are needed improve robustness MM. Diamond-like Carbon (DLC) film...
Abstract The very high luminosity run foreseen at the Z -pole for FCC-ee will allow detection in decays of new particles with low couplings to Standard Model. These can have measurable flight paths before they decay. If timing and position decay vertex be measured precision, mass such by exploiting constrained kinematics an $$e^+e^-$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:msup> <mml:mi>e</mml:mi> <mml:mo>+</mml:mo> </mml:msup> <mml:mo>-</mml:mo>...
Abstract PICOSEC Micromegas (MM) is a precise timing gaseous detector based on Cherenkov radiator coupled with semi-transparent photocathode and an MM amplifying structure. The concept was successfully demonstrated through single-channel prototype, achieving sub-25 ps time resolution Minimum Ionizing Particles (MIPs). A series of studies followed, aimed at developing robust, large-area, scalable detectors high resolution, complemented by specialized fast-response readout electronics. This...
