Computing tools for effective field theories: SMEFT-Tools 2022 Workshop Report, 14–16th September 2022, Zürich / Aebischer, Jason (ed.) (Zurich U.) ; Fael, Matteo (ed.) (CERN) ; Fuentes-Martín, Javier (ed.) (CAFPE, Granada ; Granada U., Theor. Phys. Astrophys.) ; Thomsen, Anders Eller (ed.) (Basel U.) ; Virto, Javier (ed.) (U.

Astrophys.) et al.
In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In order to discuss present and future prospects concerning automated tools in this field, the SMEFT-Tools 2022 workshop was held at the University of Zurich from 14th-16th September 2022. [...]

50 Years of Quantum Chromodynamics / Gross, Franz (Jefferson Lab ; William-Mary Coll.) ; Klempt, Eberhard (Bonn U., HISKP) ; Brodsky, Stanley J. (SLAC) ; Buras, Andrzej J. (TUM-IAS, Munich) ; Burkert, Volker D. (Jefferson Lab) ; Heinrich, Gudrun (KIT, Karlsruhe, TP) ; Jakobs, Karl (Freiburg U.) ; Meyer, Curtis A. (Carnegie Mellon U.) ; Orginos, Kostas (Jefferson Lab ; William-Mary Coll.) ; Strickland, Michael (Kent State U.) et al.
This paper presents a comprehensive review of both the theory and experimental successes of Quantum Chromodynamics, starting with its emergence as a well defined theory in 1972-73 and following developments and results up to the present day. Topics include a review of the earliest theoretical and experimental foundations; the fundamental constants of QCD; an introductory discussion of lattice QCD, the only known method for obtaining exact predictions from QCD; methods for approximating QCD, with special focus on effective field theories; QCD under extreme conditions; measurements and predictions of meson and baryon states; a special discussion of the structure of the nucleon; techniques for study of QCD at high energy, including treatment of jets and showers; measurements at colliders; weak decays and quark mixing; and a section on the future, which discusses new experimental facilities or upgrades currently funded.

Next-to-leading-order QCD matching for ∆F = 2 processes in scalar leptoquark models / Crivellin, Andreas (Zurich U. ; PSI, Villigen ; CERN) ; Eguren, Jordi Folch (ICC, Barcelona U. ; Dortmund U.) ; Virto, Javier (ICC, Barcelona U.)
Leptoquarks provide viable solutions to the flavour anomalies, i.e. they can explain the tensions between the measurements and the Standard Model predictions of the anomalous magnetic moment of the muon as well as $b\to s\ell^+\ell^-$ and $b\to c\tau\nu$ processes. [...]

The CKM parameters in the SMEFT / Descotes-Genon, Sébastien (Orsay, LPT) ; Falkowski, Adam (Orsay, LPT) ; Fedele, Marco (ICC, Barcelona U.) ; González-Alonso, Martín (CERN) ; Virto, Javier (Munich, Tech. U. ; MIT, Cambridge, CTP)
The extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix from flavour observables can be affected by physics beyond the Standard Model (SM). We provide a general roadmap to take this into account, which we apply to the case of the Standard Model Effective Field Theory (SMEFT). [...]

Gauge-invariant implications of the LHCb measurements on lepton-flavor nonuniversality / Celis, Alejandro (Munich U. ; Munich U., ASC) ; Fuentes-Martin, Javier (Valencia U., IFIC) ; Vicente, Avelino (Valencia U., IFIC) ; Virto, Javier (U. Bern, AEC)
We study the implications of the recent measurements of $R_K$ and $R_{K^*}$ by the LHCb collaboration. We do that by adopting a model-independent approach based on the Standard Model Effective Field Theory (SMEFT), in which the dominant new physics effects are encoded in the coefficients of dimension-six operators respecting the full Standard Model (SM) gauge symmetry.

Optimizing the basis of B → K*l+l- observables in the full kinematic range / Descotes-Genon, Sébastien (Orsay, LPT) ; Matias, Joaquim (Barcelona, Autonoma U.) ; Virto, Javier (Siegen U.)
We discuss the impact of recent LHCb data on the B -> K* mu+mu- decay for New Physics searches. We use an optimised set of observables with a limited sensitivity to hadronic inputs (form factors), leading to a significant deviation from the Standard Model for the semileptonic operator O9. [...]

Flavor Physics in the Quark Sector / Antonelli, Mario (Frascati) ; Asner, David Mark (Carleton U.) ; Bauer, D. (Imperial Coll., London) ; Becher, Thomas G. (Fermilab) ; Beneke, M. (Aachen, Tech. Hochsch.) ; Bevan, Adrian John (Queen Mary, U. of London) ; Blanke, Monika (Munich, Max Planck Inst. ; Munich, Tech. U.) ; Bloise, C. (Frascati) ; Bona, Marcella (CERN) ; Bondar, Alexander E. (Novosibirsk, IYF) et al.
One of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor and measurements and theoretical interpretations of their results have advanced tremendously: apart from masses and quantum numbers of flavor particles, there now exist detailed measurements of the characteristics of their interactions allowing stringent tests of Standard Model predictions. Among the most interesting phenomena of flavor physics is the violation of the CP symmetry that has been subtle and difficult to explore. [...]
