Description
We report on a first search for production of Higgs bosons decaying into neutral long-lived particles (NLLP) which each decay to a bbbar pair, using 3.6 fb^-1 of data recorded with the D0 detector at the Fermilab Tevatron collider. We search for pairs of displaced vertices in the tracking detector at radii in the range 1.6--20 cm from the beam axis. No significant excess is observed above background, and upper limits are set on the production rate in a hidden-valley benchmark model for a range of Higgs boson masses and NLLP masses and lifetimes.
We report on a first search for production of the lightest neutral CP-even
Higgs boson (h) in the next-to-minimal
supersymmetric standard model, where h decays to a pair of neutral
pseudoscalar Higgs bosons (a), using 4.2/fb of data
recorded with the D0 detector at Fermilab. The a bosons are required to
either both decay to mu^+mu^- or one to
mu^+mu^- and the other to tau^+tau^-. No significant signal is observed, and we set limits on its production as functions of M_a and M_h.
