  In this paper we discuss search strategies at the LHC for light electroweak
gauginos which are mostly Wino-like, Higgsino-like or an admixture. These
states are typically degenerate with decay products that are less energetic and
hence difficult to detect. In addition, their production cross-sections at a
hadron collider are suppressed compared to colored states such as the gluinos.
In order to detect these states one needs to trigger on initial or final state
radiation. Many previous analyses have focussed on mono-jet and mono-photon
triggers. In the paper we argue and show that these triggers are unlikely to
succeed, due to the large background from QCD backgrounds for the mono-jet
searches and the fact that the $p_T$ distribution of the mono-photons are
rapidly decreasing functions of $p_T$. We show this with both an analytic
calculation of photons in the initial state radiation and also a detailed
numerical analysis. We then argue that mono-Z triggers, from Z decaying into
charged leptons may well provide the best search strategy, in particular for
Higgsino-like and mixed cases.
