A search for the exotic meson X(5568) decaying into the B_{s}^{0}π^{±} final state is performed using data corresponding to 9.6  fb^{-1} from pp[over ¯] collisions at sqrt[s]=1960  GeV recorded by the Collider Detector at Fermilab. No evidence for this state is found and an upper limit of 6.7% at the 95% confidence level is set on the fraction of B_{s}^{0} produced through the X(5568)→B_{s}^{0}π^{±} process.

Upper limits on the number of signal events, with properties corresponding to those reported by D0, and on the X production rate relative to B_{s}^{0} mesons, ρ_{X), were determined at 95% confidence level.

Tetraquarks with open charm flavor

Inspired by the recent report of the exotic states $X_{0}(2900)$ and $X_{1}(2900)$ with four different quark flavors in the $D^{-}K^{+}$ invariant mass distributions of the decay process

Mass spectrum and strong decays of tetraquark $${\bar{c}}{\bar{s}} qq$$ states

We systematically study the mass spectrum and strong decays of the S-wave $\bar c\bar s q q$ states in the compact tetraquark scenario with the quark model. The key ingredients of the model are the

Monte-Carlo based QCD sum rules analysis of X 0(2900) and X 1(2900)

Motivated by the very recent discovery of fully open-flavor exotic states $X_0(2900)$ and $X_1(2900)$ by the LHCb Collaboration, we study possible interpretations of these exotic states by QCD Sum

Weak decays of stable open-bottom tetraquark by SU(3) symmetry analysis

The exotic state X(5568) which was observed by D0 Collaboration is very likely to be a tetraquark state with four different valence quark flavors, though the existence was not confirmed by other

We measure the B0 − B0 mixing frequency ∆md using ∼ 6000 B0 → D−(K+π−π−)π+ candidates from 36 pb−1 of data taken in physics runs of the LHCb experiment in 2010. We use opposite and same side tagging
