Accumulating Evidence for Nonstandard Leptonic Decays of Ds Mesons
- 1. Theoretical Physics Department, Fermi National Accelerator Laboratory, Batavia, Illinois 60510-0500 (United States)
Description
The measured rate for Ds+→l+ν decays, where l is a muon or tau, is larger than the standard model prediction, which relies on lattice QCD, at the 3.8σ level. We discuss how robust the theoretical prediction is, and we show that the discrepancy with experiment may be explained by a charged Higgs boson or a leptoquark
