Measurement of psi(2S) meson production in pp collisions at root s = 7TeV (vol 72, 2100, 2012)

Abstract

This erratum corrects measurements of the prompt and secondary (from-b) psi (2S) production cross-sections in the forward region in pp collisions at root s = 7TeV. The original measurements were performed using data collected with the LHCb detector in 2010 and were published in the original article. Corrected results for prompt psi(2S) and psi(2S)from-b in the kinematic range pT(psi(2S)) < 16GeV/c and 2.0 < y(psi(2S)) < 4.5 are where the last uncertainty on the prompt cross-section is due to the unknown psi(2S) polarization. With the corrected psi (2S)-from-b cross-section the inclusive branching fraction is updated by
