Abstract

We present searches for the standard model Higgs boson using up to 9.7 fb⁻¹ of $p \bar{p}$ $p\bar p$ 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 (M_H) 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 < M_H < 101 GeV and 157 GeV < M_H < 178 GeV, with an expected exclusion in the range 155 GeV < M_H < 175 GeV. An excess of data of about two Gaussian standard deviations is seen in the range 120 GeV < M_H < 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 $b \bar{b}$ $b\bar b$ at the Tevatron.
