Abstract: | A search for $B_s^0 o overline{D}^{0} f_{0}(980)$ decays is performed
using $3.0, {
m fb}^{-1}$ of $pp$ collision data recorded by the LHCb
experiment during 2011 and 2012. The $f_{0}(980)$ meson is reconstructed
through its decay to the $pi^{+}pi^{-}$ final state in the mass window $900,
{
m MeV}/c^{2} < m(pi^{+}pi^{-}) < 1080, {
m MeV}/c^{2}$. No significant
signal is observed. The first upper limits on the branching fraction of
$mathcal{B}(B_s^0 o overline{D}^{0} f_{0}(980)) < 3.1,(3.4) imes
10^{-6}$ are set at $90,\%$ ($95,\%$) confidence level. |
