dc.descriptionThough LEP II direct searches still cannot exclude a chargino nearly degenerate with the lightest neutralino if their mass is only slightly above half of the Z boson mass, it can be excluded indirectly analyzing precision data. In this particular limit simple analytical formulas for oblique electroweak radiative corrections are presented.
dc.description6 pages, latex, 2 figures included; published on PLB. Bounds on chargino mass are improved; two references are added
