EPS-HEP / Search for long-lived scalar particles in B decays at LHCb

DM: The presence of dark matter is known from cosmological observations yet it has so far escaped direct detection. As a consequence there has been renewed interet in hidden-sector models that predict new particles that are singlets with respect to the Standard Model (SM) gauge bosons and thus interact very weakly with the Standard Model particles. The LHCb experiment allows to search for these dark-sector particles in the GeV mass range using rare B meson decays, thanks to its low trigger thresholds, and excellent tracking and particle identification performance. Recent results from LHCb on searches for dark-sector particles are presented.
