Impact of Higgs-Boson measurements on SMEFT Fits
/ De Blas Mateo, Jorge (Universidad de Granada (ES)) ; Goncalves, Angelica (Florida State University (USA)) ; Miralles, Victor (University of Manchester (UK)) ; Reina, Laura (Florida State University (USA)) ; Silvestrini, Luca (Sapienza Universita e INFN, Roma I (IT)) ; Valli, Mauro (Sapienza Universita and INFN, Roma I (IT))
We present current bounds on SMEFT operators that are mainly constrained by Higgs-boson observables, under different assumptions for the flavour structure of the UV theory. We investigate how the accuracy reached through a dedicated Higgs-boson precision physics program is starting to have a major impact in setting a lower bound on the scale of new physics, and we discuss the relevance of considering the scale evolution of the SMEFT coefficients in this context.

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 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.

Overview and theoretical prospects for CKM matrix and CP violation from the UTfit Collaboration

Precision studies of the Cabibbo-Kobayashi-Maskawa matrix offer a very important testbed of the Standard Model (SM).In light of new inputs and measurements, in this proceeding we review the status of the Unitarity Triangle as a fundamental tool to uncover New Physics. We report the results of the latest SM global fits performed by the UTfit Collaboration including all the up-to-date experimental and theoretical inputs as for the Summer 2023 release.We also update the stringent constraints on New Physics from the generalized $|\Delta F| = 2$ effective Hamiltonian.

Global analysis of charm mixing parameters and determination of the CKM angle $\gamma$
/ Betti, F. (U. Edinburgh (main)) ; Bona, M. (Queen Mary, U. of London) ; Ciuchini, M. (INFN, Rome3) ; Derkach, D. (Higher Sch. of Economics, Moscow) ; Di Palma, R.

We present an updated global analysis of beauty decays sensitive to the angle $\gamma$ of the Cabibbo-Kobayashi-Maskawa matrix and of $D$-meson mixing data in the framework of approximate universality, in which CP violation in $D-\overline{D}$ mixing is described in terms of two universal weak phases corresponding to dispersive and absorptive contributions. We extract the fundamental theoretical parameters determining absorptive and dispersive contributions to $D$ meson mixing and CP violation, together with the angle $\gamma$. [...]
