Measurement of the branching ratios psi ' -> e(+)e(-), psi ' -> J/psi pi(0) pi(0) and psi ' -> J/psi eta

2000
We have determined the following psi' branching ratios using the large event sample collected by Fermilab experiment E835 in the reaction -->psi': B(psi'--> e(+)e(-)) = (7.4 +/- 0.2 +/- 0.7) x 10(-3), B(psi'--> J/psi pi(0)pi(0)) = (18.7 +/- 0.9 +/- 1.3)% and B(psi'--> J/psi eta) = (4.1 +/- 0.3 +/- 0.5)%.

Computing \(\psi(x)\)

1998
Summary: ``Let \(\Lambda\) denote the von Mangoldt function and \(\psi(x)=\sum_{n \leq x} \Lambda(n)\). We describe an elementary method for computing isolated values of \(\psi(x)\). The complexity of the algorithm is \(O(x^{2/3}(\log\log x)^{1/3})\) time and \(O(x^{1/3}(\log\log x)^{2/3})\) space. A table of values of \(\psi(x)\) for \(x\) up to \(10^{
