Measurement of the ratio of prompt χc to J/ψ production in pp collisions at s=7 TeV
R. Aaij, C. Abellán Beteta, B. Adeva, M. Adinolfi et autres
The prompt production of charmonium χ c and J /ψ states is studied in proton-proton collisions at a centre-of-mass energy of √ s = 7 TeV at the Large Hadron Collider.The χ c and J /ψ mesons are identified through their decays …
