“…The mass of h 0 can be calculated in terms of the two parameters of the Higgs sector mentioned above (m A 0 and tan β) and other MSSM soft-supersymmetry-breaking parameters that affect the Higgs mass through virtual loops [31,32,33,34,35,36,37,38,39,40]. The largest contribution to the one-loop radiative corrections is enhanced by a factor of m 4 t and grows logarithmically with the stop mass.…”

“…The largest contribution to the one-loop radiative corrections is enhanced by a factor of m 4 t and grows logarithmically with the stop mass. Thus, higher-order radiative corrections can be non-negligible for large stop masses, in which case the large logarithms must be resummed using renormalization group techniques [35,36,37,38,39,40].…”

In the infrared fixed point (IFP) scenario of the minimal supersymmetric model (MSSM), the top-quark mass and other physical quantities of the low-energy theory are insensitive to the values of the parameters of the theory at some high energy scale. In this framework we evaluate the light CP-even Higgs mass, m h 0 , taking into account some important effects that had not been previously considered. In particular, the supersymmetric correction to the relation between the running and the physical top-quark masses lowers the value of tan β, thereby implying a lower predicted value of m h 0 . Assuming a supersymmetric threshold of M S ≤ 1 TeV and M t = 175 GeV, we find an upper bound of m h 0 ≤ 97 ± 2 GeV; the most plausible value of m h 0 lies somewhat below the upper bound. This places the Higgs boson in the IFP scenario well within the reach of the LEP-2 Higgs search.

We construct composite Higgs models admitting a weakly coupled Seiberg dual description. We focus on the possibility that only the up-type Higgs is an elementary field, while the down-type Higgs arises as a composite hadron. The model, based on a confining SQCD theory, breaks supersymmetry and electroweak symmetry dynamically and calculably. This simultaneously solves the µ/B µ problem and explains the smallness of the bottom and tau masses compared to the top mass. The proposal is then applied to a class of models where the same confining dynamics is used to generate the Standard Model flavor hierarchy by quark and lepton compositeness. This provides a unified framework for flavor, supersymmetry breaking and electroweak physics. The weakly coupled dual is used to explicitly compute the MSSM parameters in terms of a few microscopic couplings, giving interesting relations between the electroweak and soft parameters. The RG evolution down to the TeV scale is obtained and salient phenomenological predictions of this class of "single-sector" models are discussed.

The search for the Higgs boson was one of the most relevant issues of the final years of LEP running at high energies. An excess of 3σ beyond the background expectation has been found, consistent with the production of the Higgs boson with a mass near 115 GeV/c2. At the upgraded TeVatron and at LHC the search for the Higgs boson will continue. At TeVatron Higgs bosons can be detected with masses up to 180 GeV with an assumed total integrated luminosity of 20 fb—1. LHC has the potential to discover the Higgs boson in many different decay channels for Higgs masses up to 1 TeV. It will be possible to measure Higgs boson parameters, such as mass, width, and couplings to fermions and bosons. The results from Higgs searches at LEP2 and the possibilities for searches at hadron colliders will be reviewed.
