The Chances to Produce and Detect the b-b-ubar-dbar Tetraquark at LHC

In the LHC collider a significant rate of events with double parton scattering is expected. This will be the leading mechanism for production of two b-bbar pairs. We estimate the probability of binding two b quarks into a diquark and the probability of dressing this diquark into a b-b-ubar-dbar ISP=01+ tetraquark. Calculations shows that that this bound state of two B mesons is stable against the strong interaction and has a life time of the order of ps. We estimate that the production rate at luminosity L=0.1 events per second will be about 6 tetraquarks per hour or more.Comment: Contributed talk at the XVIII European Conference on Few-Body Problems in Physics, September 8-14, Bled, Slovenia, 4 pages LaTe

The Chances to Produce and Detect the bbū ¯ d Tetraquark at LHC

Abstract. In the LHC collider a significant rate of events with double parton scattering is expected. This will be the leading mechanism for production of two b ¯ b pairs. We estimate the probability of binding two b quarks into a diquark and the probability of dressing this diquark into a bbū ¯ d (IS P = 01 +) tetraquark. Calculations shows that that this bound state of two B mesons is stable against the strong interaction and has a life time of the order of ps. We estimate that the production rate at luminosity L = 0.1 events per second will be about 6 tetraquarks per hour or more.
