Live Blogging: #Higgs Boson

One day before: Update from CDF/D0 Tevatron's experiments CDF and D0 just published their most up-to-date searches for the Standard Model Higgs boson. You can read the preprint here [arXiv:1207.0449] and take a closer look at the bonanza of new plots here.What they see is a mild excess especially in the h->bb decay channel, for which … Continue reading Live Blogging: #Higgs Boson

Accumulating evidence for nonstandard leptonic decays of Ds mesons

from arXiv:0803.0512v2 [hep-ph] The measured rate for D_s -> l nu decays, where l is a muon or tau, is larger than the standard model prediction, which relies on lattice QCD, at the 3.8 sigma level. We discuss how robust the theoretical prediction is, and we show that the discrepancy with experiment may be explained … Continue reading Accumulating evidence for nonstandard leptonic decays of Ds mesons
