Future Circular Collider Feasibility Study Report Volume 2 : Accelerators, technical infrastructure and safety

In response to the 2020 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) Feasibility Study was launched as an international collaboration hosted by CERN. The FCC ‘integrated programme’, described in this report, in a first stage consists of a highest-luminosity electron-positron collider, FCC-ee, serving as Higgs, top and electroweak factory, with a subsequent energy-frontier proton-proton collider, FCC-hh, as the second stage. The FCC-ee is designed to operate at four baseline centre-of-mass energies, corresponding to the Z pole, the WW pair production threshold, the ZH production peak, and the top/anti-top production threshold, always delivering the highest possible luminosities to four experiments.

Volume 3 of the FCC Feasibility Report presents studies related to civil engineering, the development of a project implementation scenario, and environmental and sustainability aspects. The report details the iterative improvements made to the civil engineering concepts since 2018, taking into account subsurface conditions, accelerator and experiment requirements, and territorial considerations.

Volume 1 of the FCC Feasibility Report presents an overview of the physics case, experimental programme, and detector concepts for the Future Circular Collider (FCC). This volume outlines how the FCC would address some of the most profound open questions in particle physics, from precision studies of the Higgs and EW bosons and of the top quark, to the exploration of physics beyond the Standard Model.

Focus topics for the ECFA study on Higgs / Top / EW factories
/ de Blas, Jorge (Granada U.) ; Koppenburg, Patrick (Nikhef, Amsterdam) ; List, Jenny (DESY) ; Maltoni, Fabio (Louvain U.) ; Maestre, Juan Alcaraz (Madrid, CIEMAT) ; Alimena, Juliette (DESY) ; Alison, John (Carnegie Mellon U.) ; Azzi, Patrizia (INFN, Padua) ; Azzurri, Paolo (INFN, Pisa) ; Bagnaschi, Emanuele (CERN ; INFN, Italy) et al.
In order to stimulate new engagement and trigger some concrete studies in areas where further work would be beneficial towards fully understanding the physics potential of an $e^+e^-$ Higgs / Top / Electroweak factory, we propose to define a set of focus topics. [...]

B+ -> K+ nu nubar and other highlights from Belle II
/ Manoni, Elisa (speaker) (Universita e INFN, Perugia (IT))
In this seminar, we will first survey selected first physics highlights from the Belle II experiment at the SuperKEKB collider in Japan, before going in depth on our recent measurement of $B^+\rightarrow K^+ \nu\bar{\nu}$. The decay $B^+\rightarrow K^+ \nu\bar{\nu}$ is mediated by a flavor-changing neutral current. In the Standard Model, the predicted branching fraction is about $6\times 10^{-5}$, while enhancements are foreseen in New Physics scenarios.We search for this rare decay in a 362 fb$^{-1}$ sample of electron-positron collisions at the $\Upsilon(4S)$ resonance.
