Vietnam Flavour Physics Conference: Aims and Goals
These aims and goals for the Flavour Physics community as a whole have been distilled from the discussions at the 2022 conference.
1. Probing Physics Beyond the Standard Model (BSM) through Rare Decays
Explore rare processes such as B0(s) → μ+μ− and B → K* ℓ+ℓ− that may reveal deviations from Standard Model predictions, potentially signalling the presence of new, heavy particles.
2. Understanding CP Violation and the Matter-Antimatter Asymmetry
Improve precision in measurements of CP-violating observables in meson decays to elucidate the origins of the baryon asymmetry in the universe.
3. Systematic Study of Flavour Anomalies
Investigate persistent anomalies in observables such as R_D(*), R_K(*), and angular distributions in semileptonic B-decays, to determine whether they represent statistical fluctuations, underestimated hadronic effects, or genuine signs of new physics.
4. Advancing Effective Field Theories and Lattice QCD Techniques
Enhance theoretical tools like QCD factorisation and lattice QCD to better quantify hadronic matrix elements, including power corrections and form factors, especially in decays involving light or fast particles.
5. Precision Determination of CKM Matrix Elements
Refine the measurements of |Vcb|, |Vub|, and their ratios through inclusive and exclusive semileptonic decays to test the unitarity of the CKM matrix and identify potential new sources of flavour violation.
6. Testing Lepton Flavour Universality and Searching for Violations
Conduct high-precision comparisons of processes involving electrons, muons, and taus to scrutinise the principle of lepton flavour universality and uncover possible violations.
7. Constraining and Constructing Flavour Models
Interpret observed flavour structures in terms of underlying symmetries or dynamics, possibly linked to the origin of the Yukawa couplings or grand unified frameworks, and constrain such models through data.
8. Pursuing Charged Lepton Flavour Violation (CLFV)
Explore processes such as μ → eγ, μ → e conversion, and τ → μγ as probes of physics at high scales where such violations are naturally predicted in many BSM scenarios.
9. Exploiting Complementarity of Experimental Facilities
Utilise the strengths of various platforms—such as LHCb, Belle II, BESIII, and future muon and kaon experiments—to provide complementary constraints and explore otherwise inaccessible flavour transitions.
10. Improving Theoretical Control of QED and QCD Corrections
Address challenges in precisely modelling electromagnetic and strong interaction effects, including radiative corrections and structure-dependent contributions, essential for reducing uncertainties in precision observables.
11. Developing Infrastructure for Long-Term Precision Studies
Invest in computational and experimental infrastructure (including detector upgrades and software development) necessary to sustain and advance long-term precision programmes in flavour physics.
12. Preparing for Interpretation of Future Discoveries
Maintain a robust theoretical framework capable of interpreting potential new particle signals discovered at future colliders (e.g., FCC, muon colliders) within the flavour sector, to distinguish between competing BSM models.
