The proposed Future Circular Collider (FCC) integrated programme consists of two stages: An electron–positron collider serving as a highest-luminosity Higgs-boson, electroweak and top-quark factory, followed by a proton–proton collider with a collision energy around 100 TeV. In 2021, the CERN Council initiated the FCC Feasibility Study. This study covered, inter alia, physics objectives and...
SuperKEKB is a positron-electron collider with a nano-beam scheme. The nano-beam scheme allows the extremely low beta function at the interaction point (IP) compared to the bunch length, namely ordinary colliders. The beta function at the IP is less than 1 mm which is the smallest value among the previous colliders. Recent results on beam-beam interactions, beam injection under the influence...
As part of the European Strategy in Particle Physics Update (ESPPU) the particle physics community is evaluating the options for the next flagship project at CERN. Immense interest in exploring the physics of the Higgs sector and the potential for discovering new physics at high energy is at the core of our motivation for pursuing the next particle collider. The Linear Collider Vision...
