The Cut & Enhance method : selecting clusters of galaxies from the SDSS commissioning data
Tomotsugu Goto, Maki Sekiguchi, Robert C. Nichol +8
We describe an automated method, the Cut & Enhance method (CE) for detecting clusters of galaxies in multi-color optical imaging surveys. This method uses simple color cuts, combin…
Measurement of Br(Bbar -> D+l-nubar) and Determination of |Vcb|
Belle Collaboration, K. Abe
We present a measurement of the branching fraction for the semileptonic B decay Bbar -> D+l-nubar, where l- can be either an electron or a muon. We find Gamma(Bbar -> D+l-nubar)= (…
Non-perturbative renormalization in domain-wall QCD by Schrödinger functional scheme
PACS Collaboration, S. Aoki, Y. Aoki +13
We formulate and numerically test the Schrödinger functional scheme for domain-wall QCD. We then apply it to a non-perturbative calculation of the renormalization factors for vecto…
Method for Determination of in Neutrino Oscillation Appearance Experiments
Takaaki Kajita, Hisakazu Minakata, Hiroshi Nunokawa
We point out that determination of the MNS matrix element |U_{e3}| = s_{13} in long-baseline ν_μ \to ν_e neutrino oscillation experiments suffers from large intrinsic uncertainty d…
Polynomial Hybrid Monte Carlo algorithm for lattice QCD with an odd number of flavors
JLQCD Collaboration, S. Aoki, R. Burkhalter +15
We present a polynomial hybrid Monte Carlo (PHMC) algorithm for lattice QCD with odd numbers of flavors of O(a)-improved Wilson quark action. The algorithm makes use of the non-Her…
Charmonium Spectrum from Quenched Anisotropic Lattice QCD
PACS Collaboration, M. Okamoto, S. Aoki +16
We present a detailed study of the charmonium spectrum using anisotropic lattice QCD. We first derive a tree-level improved clover quark action on the anisotropic lattice for arbit…
