Rare and forbidden Kaon decays - 2
- Yee Hsiung (National Taiwan University (TW))
During last years quite significant statistics of kaon decays has been accumulated by “OKA” setup which is working in the 20 GeV/c RF-separated secondary $K^+$ beam of the U-70 synchrotron. About 7 billions of kaon decays have been detected. Results on several radiative decays have been obtained.
On the selected ~100K of $K_{\mu2\gamma}$ decays with $25<...
$K_L\rightarrow \pi^0 \gamma $ is forbidden by the standard model
because this decay mode threatens the Lorentz invariance and gauge principle.
There have been various experimental tests of the Lorentz invariance
using optical cavities, however, experimental tests in the high energy
regime are also useful probes of New Physics.
In spite of its interesting opportunity,
neither...
I discuss generic effects of new physics on the rare decay modes KL → π0νν̄ and K+ → π+νν̄ from the point of view of the neutrino sector. I consider left-handed neutrino couplings; right handed neutrino couplings; neutrino lepton flavour violating (LFV) interactions; and ∆I = 3/2 interactions. The first of these cases has been studied before as it covers many new physics extensions of the...
