Production of the Exotic $1^{--}$ Hadrons $\varphi (2170)$, 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 $\varphi (2170)$, X(4260) and $Y_b(10890)$ at the hadron colliders LHC and the Tevatron. These hadrons are tetraquark (four-quark) candidates, with a hidden $s\bar{s}$, $c\bar{c}$ and $b\bar{b}$ quark pair, respectively. In deriving the distributions and cross sections, we include the order ${\alpha }_s$ 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. Taking into account the data on the production and decays of these vector hadrons from the $e^{+}{e}^{-}$ experiments, we present the production rates for the processes $pp(\bar{p})\to \varphi (2170)(\to \varphi (1020){\pi }^{+}{\pi }^{-}\to K^{+}{K}^{-}{\pi }^{+}{\pi }^{-})+...$, $pp(\bar{p})\to X(4260)(\to J/\psi {\pi }^{+}{\pi }^{-}\to {\mu }^{+}{\mu }^{-}{\pi }^{+}{\pi }^{-})+...$, and $pp(\bar{p})\to Y_b(10890)(\to ({\rm Y}(1S),{\rm Y}(2S),{\rm Y}(3S)){\pi }^{+}{\pi }^{-}\to {\mu }^{+}{\mu }^{-}{\pi }^{+}{\pi }^{-})+...$. Their measurements at the hadron colliders will provide new experimental avenues to explore the underlying dynamics of these hadrons.
