Variable space search for graph coloring

Nicolas Zufferey, Matthieu Plumettaz

Let G = (V, E) be a graph with vertex set V and edge set E. The k-coloring problem is to assign a color (a number chosen in {1, ..., k}) to each vertex of G so that no edge has both endpoints with the same color. We propose a new local search methodology, ...

New search for τ → μ γ and τ → e γ decays at Belle

Olivier Schneider, Aurelio Bay, Chao Wang, Sun Hee Kim

We report on a search for the lepton flavor violating τ- → μ- γ and τ- → e- γ decays based on 535 fb-1 of data accumulated at the Belle experiment. No signal is found and we set 90% confidence level upper limits on the branching ratios B (τ- → μ- γ) < 4.5 ...

Observation of B±→ψ(2S)π± and search for direct CP violation

Olivier Schneider, Aurelio Bay, Mingkui Wang, Chao Wang, Tagir Aushev, Vladislav Balagura, Sun Hee Kim, Xiao Wang

We report the first observation of B±→ψ(2S)π±, a Cabibbo- and color-suppressed decay. This analysis is based on 657×106 BB̄ events collected at the Υ(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. The measured branching ...

Search for B0→J/ψ decays

Olivier Schneider, Aurelio Bay, Chao Wang, Tagir Aushev, Sun Hee Kim, Xiao Wang, Jing Li

We report a search for the decay B0→J/ψ, using a sample of 657×106 BB̄ pairs collected with the Belle detector at the Υ(4S) resonance. No statistically significant signal is found and an upper limit for the branching fraction is determined to be B(B0→J/ψ)< ...
