Search for structure in the $B_s^0{\pi }^{\pm }$ invariant mass spectrum

Abstract

The $B_s^0{\pi }^{\pm }$ invariant mass distribution is investigated in order to search for possible exotic meson states. The analysis is based on a data sample recorded with the LHCb detector corresponding to $3$ fb${}^{-1}$ of $pp$ collision data at $\sqrt{s}=7$ and $8$ TeV. No significant excess is found, and upper limits are set on the production rate of the claimed $X(5568)$ state within the LHCb acceptance. Upper limits are also set as a function of the mass and width of a possible exotic meson decaying to the $B_s^0{\pi }^{\pm }$ final state. The same limits also apply to a possible exotic meson decaying through the chain $B_s^{\ast 0}{\pi }^{\pm }$, $B_s^{\ast 0}\to B_s^0\gamma$ where the photon is excluded from the reconstructed decays.
