  1. 23. Theoretical Review on Lepton Universality and LFV
    Dr Paride Paradisi (Valencia University, IFIC)
    24/05/2007, 09:30
    Lepton Universality and LFV
  2. 63. Kaon physics within nuMSM
    Dr Dmitry Gorbunov (INR RAS)
    24/05/2007, 10:00
    Lepton Universality and LFV
    An extension of the Standard Model by three singlet fermions with masses smaller than the electroweak scale allows to explain simultaneously neutrino oscillations, dark matter and baryon asymmetry of the Universe. We discuss here the properties of neutral leptons in this model and the ways they can be searched for in particle physics experiments. In particular, if sterile neutrinos are...

    Lepton Universality and LFV
  4. 62. Probing the lepton flavour universality with Kl2
    Venelin Kozhuharov (Univerity of Sofia "St. Kl. Ohridski")

    Lepton Universality and LFV
    The ratio $R_K = \Gamma(K^{\pm}\to e^{\pm}\nu) / \Gamma(K^{\pm}\to \mu^{\pm}\nu) $ provides a very powerful probe for the weak interactions structure. This ratio of decay rates is calculated with very high precision within the Standard Model but corrections due to the presence of New Physics could be as high as 3\%. The data obtained by the NA48 experiment in two years of data taking at...

  5. 73. Preliminary measurement of BR(ke2)/BR(kmu2) at KLOE
    Alexei Sibidanov (BINP, Novosibirsk)
    24/05/2007, 11:30
    Lepton Universality and LFV
    We present a preliminary measurement of the ratio of the purely leptonic branching ratios of the charged kaons, BR(ke2)/BR(kmu2), using a sample of about 2 fb-1 of data acquired with the KLOE detector at the Frascati \phi-factory DAFNE.

  6. 79. Lepton Universality Tests with Kaons
    Dr Rainer Wanke (Mainz University)
    24/05/2007, 11:50
    Lepton Universality and LFV
    Precision data on Kl3 and Kl2 decay rates and form factors allow us to perform significant tests of lepton universality and to constrain the strength of non-standard interactions. We discuss the present status of these tests and new-physics searches, as obtained by combining all the available results of the various kaon-physics experiments

  7. 81. Rare and forbidden decay of Charm Mesons at CLEO-c and BESIII
    Dr Haibo Li (IHEP, Beijing)
    24/05/2007, 12:20
    Lepton Universality and LFV
    In this talk, I will give a brief review on the current limits of rare and forbidden decays of Charm mesons at CLEO-c and BES experiments. The current status of BES-III project as a tau-Charm factory will be discussed. The sensitivities of the measurements for rare and forbidden Charm decays are estimated. The test of Lepton Universality and LFV in J/psi decay at BES-III are...

  8. 41. Experimental Review on Lepton Universality and LFV tests at a B-factory
    Dr Alberto Lusiani (INFN - Pisa)
    24/05/2007, 12:50
    Lepton Universality and LFV
    Since 1999, the B-factory Collaborations, Babar and Belle, have accumulated and studied large samples of tau lepton pairs. The experimental results on Lepton Universality checks and Lepton Flavour Violation searches will be reported.
