Abstract: We have observed a very sharp peak in the cross section for ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}\mathrm{hadrons}, {e}^{+}{e}^{\ensuremath{-}}$, and possibly ${\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$ at a center-of-mass energy of 3105\ifmmode\pm\else\textpm\fi{}0003 GeV The upper limit to the full width at half-maximum is 13 MeV

Heavy quarkonium production and polarization.
TL;DR: A perturbative QCD factorization formalism for the production of heavy quarkonia of large transverse momentum p(T) at collider energies is presented, which includes both the leading-power and next-to-leading-power contributions to the cross section in the m(Q)(2)/p(T)(2) expansion for heavy quarks mass m( Q).

TL;DR: In this article, the authors measured multihadron production in e+e− annihilation at center-of-mass energies between 2.6 and 7.8 GeV and found that the total hadronic cross section was approximately 2.7 times the cross section for the production of muon pairs at c.m.
