abstract
A search for charginos nearly mass degenerate with the lightest neutralino is performed with the data collected by the ALEPH detector at LEP, at centre-of-mass energies between 189 and 209 GeV, corresponding to an integrated luminosity of 628 pb-1. The analysis is based on the detection of isolated and energetic initial state radiation photons, produced in association with chargino pairs whose decay products have little visible energy. The number of candidate events observed is in agreement with that expected from Standard Model background sources. These results are combined with those of other direct searches for charginos, and a lower limit of 88 GeV/c2 at 95 % confidence level is derived for the chargino mass in the case of heavy sfermions, irrespective of the chargino-neutralino mass difference.

Non-Holomorphic Impact on $t-b-\tau$ Yukawa Unification in minimal GMSB
Non-holomorphic terms enable t-b-τ Yukawa unification in minimal GMSB for μ>0, producing solutions with Higgs-mass consistency, charginos as light as 120 GeV, and staus around 600 GeV that are testable via lifetime and compressed-spectra searches.
