In this research, YBa2Cu3O7-d (0 < d < 1) nanocrystalite superconductor was prepared by mechanochemical alloying method. We synthesized YBa2Cu3O7-d via mixing the BaCO3, Y2O3, CuO powders and milling in SPEX 8000 for 5h with weight ratio of ball to powder 10:1 and steel balls of 11mm diameter, followed by heating for 4h at 850 ˚C. The superconductor phase formation process was completed with si...

We have searched for the charmless hadronic decay of B mesons into two neutral pions. Using 9.13 fb taken at the Υ(4S) with the CLEO detector, we obtain an improved upper limit for the branching fraction B(B → ππ) < 5.7 × 10 at the 90% confidence level.
