title: Production of the exotic 1(--) hadrons ϕ(2170), X(4260), and Y(b)(10890) at the LHC and Tevatron via the Drell-Yan mechanism.
abstract: We calculate the Drell-Yan production cross sections and differential distributions in the transverse momentum and rapidity of the J(PC) = 1(--) exotic hadrons ϕ(2170), X(4260), and Y(b)(10890) at the LHC and the Tevatron. These hadrons are tetraquark (four-quark) candidates, with a hidden ss, cc, and bb quark pair, respectively. In deriving the distributions, we include the order α(s) QCD corrections, resum the large logarithms in the small transverse momentum region in the impact-parameter formalism, and use the state of the art parton distribution functions. Production rates for the processes pp(p) → ϕ(2170)× (→ ϕ(1020)π+ π- → K+ K- π+ π-) +…, pp(p) → X(4260)(→J/ψπ+ π- → μ+ μ- π+ π-)+…, and pp(p) → Y(b)(10890)(→ Υ(1S,2S,3S)π+ π- → μ+ μ- π+ π-) +… are presented. Their measurements will help in understanding the dynamics of these exotic hadrons.
