We present searches for the standard model Higgs boson using up to 9.7 fb−1 of collisions collected with the D0 detector at Fermi lab. The analyses consist in a series of distinct final states and are sensitive to Higgs boson masses (MH) ranging from 90 GeV to 200 GeV. These analyses are combined and allow to exclude a standard model Higgs boson at 95% Confidence Level (C.L.) in the range 90 GeV < MH < 101 GeV and 157 GeV < MH < 178 GeV, with an expected exclusion in the range 155 GeV < MH < 175 GeV. An excess of data of about two Gaussian standard deviations is seen in the range 120 GeV < MH < 145 GeV, consistent with the observation of a boson with a mass of 125 GeV at the Large Hadron Collider and with the evidence for a particle decaying to at the Tevatron.
