Radiative corrections in the MSSM beyond one-loop : precision observables and neutral Higgs masses / Hollik, Wolfgang F L (CERN)
Recent results on two-loop QCD corrections to electroweak precision observables and to the neutral Higgs boson masses in the Minimal Supersymmetric Standard Model are presented. Main emphasis is on the QCD corrections to electroweak precision observables via squark contributions to the rho -parameter, and on the Feynman-diagrammatic calculation of the masses of the MSSM Higgs bosons h/sup 0/, H/sup 0/ yielding the currently most precise prediction of the lightest Higgs mass m/sub h/ within the Feynman-graph approach.

The hadronic tau decay of a heavy H$^{+or-}$ in ATLAS / Assamagan, Ketevi A ; Coadou, Y
The hadronic tau decay of a heavy charged Higgs boson, H/sup +or-/ to tau nu , is considered in ATLAS. In the mass region m(H/sup +or-/) > m/sub t/, the most relevant decay channels of the charged Higgs boson are H/sup +or-/ to tb and H/sup +or-/ to tau nu . [...]

Searches for the Higgs bosons predicted by the extensions of the standard model with two Higgs-field doublets using LEP data / Locci, E (DAPNIA)
Results from 630 pb/sup -1/ collected by each of the four LEP experiments have been derived for the Higgs bosons predicted by the extensions of the standard model with two Higgs-field doublets. Limits on the masses of the neutral Higgs bosons h/sup 0/, A/sup 0/, H/sup 0/, the charged Higgs bosons H/sup +or-/, and tan beta , have been obtained by the LEP Higgs working group. [...]

Radiative corrections to pair production of charged Higgs bosons in $e^{+}e^{-}$ collisions / Guasch, J (Karlsruhe U., TTP) ; Hollik, Wolfgang F L ; Kraft, A
Charged Higgs particles are a common feature of many extensions of the Standard Model. While its existence with masses up to the TeV scale can be probed at the Tevatron Run II and LHC hadron colliders, a precise determination of its properties would have to wait for a high energy e/sup +/e/sup -/ linear collider. [...]

Stau lightest supersymmetric particle and comparison with H$^{+or-}$ phenomenology / Akeroyd, A G ; Chun, Liu ; Jeongh Yeon Song
In supersymmetric models with explicit breaking of R parity the lightest supersymmetric particle (LSP) may be the lightest stau tau /sub 1/. Such a scenario would provide a clear sign of R-parity violating SUSY, although its phenomenology may resemble that of a charged Higgs boson H/sup +or-/. [...]

Systematic study of Higgs masses in the MSSM / Ghosh, B ; Chakravarty, S
The Higgs masses in the minimal supersymmetric standard model at extremely high energies relevant to LEP2 and LHC have been studied. The results of systematic studies on Higgs masses for the possible ranges of all the parameters in the case of 1-loop radiative correction to the Higgs boson masses have been given. [...]

Determining tan beta with neutral and charged Higgs bosons at a future $e^{+} e^{-}$ linear collider / Gunion, J F ; Han, T ; Jiang, J ; Sopczak, A
The ratio of neutral Higgs field vacuum expectation values, tan beta , is one of the most important parameters to determine in either the minimal supersymmetric standard model (MSSM) or a general type-II two-Higgs doublet model (2HDM). Assuming an energy and integrated luminosity of square root s=500 GeV and L=2000 fb/sup -1/ at a future linear collider (LC), we show that a very accurate determination of tan beta will be possible for low and high tan beta values by measuring the production rates of Higgs bosons and reconstructing Higgs boson decays.

Distinguishing a minimal supersymmetric standard model Higgs boson from the SM Higgs boson at a linear collider / Carena, M S ; Haber, Howard E ; Logan, H E ; Mrenna, S
The decoupling properties of the Higgs sector in the minimal supersymmetric standard model (MSSM) imply that a light CP-even Higgs boson discovered at the Fermilab Tevatron or CERN LHC may closely resemble the standard model (SM) Higgs boson. In this paper, we investigate how precision measurements of Higgs properties at a linear collider (LC) can distinguish between a CP-even Higgs boson of the MSSM and the SM Higgs boson. [...]

SUSY Higgs at LEP / Fisk, I (Dept of Phys, California Univ, San Diego, La Jolla, CA, USA)
The results of the search at LEP for the h and A neutral Higgs bosons and the H/sup +/ and H/sup -/ charged Higgs bosons are presented from the 1998 data taken at 189 GeV center-of-mass energy and 1999 data taken at 192 GeV, 196, GeV, 200 GeV, and 202 GeV center-of-mass energies from the Aleph, Delphi, L3, and Opal collaborations as well as the combined results of the four. Together this data set constitutes nearly 900 pb/sup -1/ above 192 GeV and an additional 700 pb/sup -1/ at 189 GeV. [...]
