Lattice calculation of the zero-recoil form factor of anti-B --> D* lepton anti-neutrino: toward a model independent determination of |V(cb)|

Shoji Hashimoto, Andreas S. Kronfeld, Paul B. Mackenzie +2

We develop a new method in lattice QCD to calculate the form factor F(1) at zero recoil. This is the main theoretical ingredient needed to determine |V(cb)| from the exclusive deca…

PYTHIA 6.2 Physics and Manual

Torbjörn Sjöstrand, Leif Lönnblad, Stephen Mrenna

The PYTHIA program can be used to generate high-energy-physics `events', i.e. sets of outgoing particles produced in the interactions between two incoming particles. The objective…

Neutrinos as the messengers of CPT violation

G. Barenboim, L. Borissov, J. Lykken +1

CPT violation has the potential to explain all three existing neutrino anomalies without enlarging the neutrino sector. CPT violation in the Dirac mass terms of the three neutrino…
