Title: Review of bottomonium measurements from CMS

Abstract

We review the results on the bottomonium system from the CMS experiment at the Large Hadron Collider. Measurements have been carried out at different center-of-mass energies in proton collisions and in collisions involving heavy ions. These include precision measurements of cross sections and polarizations, shedding light on hadroproduction mechanisms, and the observation of quarkonium sequential suppression, a notable indication of quark–gluon plasma formation. The observation of the production of bottomonium pairs is also reported along with searches for new states. We close with a brief outlook of the future physics program.

  • Pion exchange in S-wave between hadrons that are themselves in a relative S-wave is shown to shift energies by hundreds of MeV, leading to deeply bound quasi-molecular states. In the case of charmed mesons D*,D1 a spectroscopy arises consistent with enigmatic charmonium states observed above 4 GeV in e+e- annihilation. A possible explanation of Y(4260) --> psi pi pi and Y(4360) --> psi' pi pi is found. We give results for all isospin and charge-conjugation combinations, and comment on flavor exotic doubly charmed states and bottomonium analogs. A search in D Dbar 3pi is recommended to test this hypothesis. Anmore » exotic 1-+ is predicted to occur in the vicinity of the Y(4260).« less

  • Within the framework of the multipole expansion in QCD it is shown that the transition from the UPSILON(3S) resonance to the spin-singlet level of bottomonium with emission of two pions, UPSILON(3S)..-->..1/sup 1/P/sub 1/..pi pi.., is suppressed by two orders of magnitude in comparison with the parton estimate used earlier, and must have a relative probability of less than 10/sup -4/. The isospin-violating single-pion transition UPSILON(3S)..-->..1/sup 1/P/sub 1/..pi../sup 0/ has an order of magnitude greater probability than the two-pion one, and can be of order 10/sup -3/ of the width of the UPSILON(3S) resonance. The reason for the small probability ofmore » the two-pion transition in question is that the anomaly in the trace of the energy-momentum tensor, which determines the width of decays of the type UPSILON'..-->..UPSILON..pi pi.., does not contribute to it.« less
  • The charmonium and bottomonium spectra computed from a potential defined from a single gauge configuration, obtained from solving the classical field equations, is discussed. The theoretical spectra shows good agreement with the measured states.A discussion of possible interpretations, within the same non-relativistic potential model, for the new charmonia states X(3872), {chi}c1(2P) and Y(4260) is performed. In particular, we give predictions for electromagnetic E1 transitions for various scenarios.
  • Recently, realistic lattice QCD calculations with 2+1 flavors of domain wall fermions and the Iwasaki gauge action have been performed by the RBC and UKQCD Collaborations. Here, results for the bottomonium spectrum computed on their gauge configurations of size 24{sup 3}x64 with a lattice spacing of approximately 0.11 fm and four different values for the light quark mass are presented. Improved lattice nonrelativistic QCD is used to treat the b quarks inside the bottomonium. The results for the radial and orbital energy splittings are found to be in good agreement with experimental measurements, indicating that systematic errors are small. Themore » calculation of the {upsilon}(2S)-{upsilon}(1S) energy splitting provides an independent determination of the lattice spacing. For the most physical ensemble it is found to be a{sup -1}=1.740(25)(19) GeV, where the first error is statistical/fitting and the second error is an estimate of the systematic errors due to the lattice nonrelativistic QCD action.« less
