Parallel talks 4: Flavour & Precision Physics
- Chen Wu (Osaka University)
We present the status of JPARC KOTO experiment to search for very rare $K_L$ decays to $\pi^0 \nu \overline{\nu}$ - an FCNC and direct $CP$ violating decay mode. KOTO has collected $K_L$ data yearly with 30 GeV high intensity proton beam on target at JPARC since 2015 until now with increasing beam power over this period up to 64.5 kW. The results from 2016-18 data published in 2021 ($ BR < 4.9...
The NA62 experiment at CERN collected the world’s largest dataset of charged
kaon decays in 2016-2018, leading to the first measurement of the Branching
Fraction of the ultra-rare K+ → π+ν¯ν decay, based on 20 candidates. This
provides evidence for the very rare K+ → π+ν¯ν decay, observed with a significance
of 3.4σ. This measurement is also used to set limits on BR(K+ → π+X),
where X is...
In recent years, the study of lepton flavour universality (LFU) violation has garnered significant attention in the field of high energy physics. The ATLAS experiment at the Large Hadron Collider (LHC) has played a crucial role in unraveling the mysteries surrounding LFU and exploring the potential implications for our understanding of the fundamental particles and interactions. In this talk,...
Electric dipole moments (EDMs) of elementary particles are powerful probes of physics beyond the Standard Model with CP violation. The reported discrepancy in the muon anomalous magnetic moment motivates us to explore to what extent new physics with CP violation to address the discrepancy is probed by ongoing and projected searches for the muon EDM. In this talk, we discuss two benchmark...
