Monte Carlo simulation for radiative kaon decays

Monte Carlo simulation for radiative kaon decays

For high precision measurements of K decays, the presence of radiated photons cannot be neglected. The Monte Carlo simulations must include the radiative corrections in order to compute the correct event counting and efficiency calculations. In this paper we briefly describe a method for simulating such decays.

Radiative Semileptonic Kaon Decays

We evaluate the matrix elements for the radiative kaon decays K → lνlγ, lνll l and K → πlνlγ (l, l = e, μ) to next-to-leading order in chiral perturbation theory. We calculate total rates and rates with several kinematical cuts and confront the results with existing data. Measurements at future kaon facilities will allow for a more detailed comparison between theory and experiment. † Address af...

Radiative Rare Kaon Decays †

We discuss theoretical issues in radiative rare kaon decays. The interest is twofold: to extract useful short-distance information and understand the underlying dynamics. We emphasize channels where either we can understand non-perturbative aspects of QCD or there is a chance to test the Standard Model.

Radiative Non – Leptonic Kaon Decays

Rare and Radiative Kaon Decays ∗

We review the status of theory and experiment of very rare and forbidden kaon decays. We then review the radiative non-leptonic decays, and the associated Dalitz pair modes. We pay particular attention to the study of long distance physics in radiative decays within the framework of chiral perturbation theory (χPT). We discuss the experiments that will run in the near future and the modes that ...
