      abstract     = {The Triplet extension of the MSSM (TMSSM) alleviates the
                      little hierarchy problem and provides a significant
                      enhancement of the loop-induced diphoton rate of the
                      lightest CP-even Higgs h. In this paper we pursue the
                      analysis of the TMSSM Higgs phenomenology by computing for
                      the first time the h into Z + gamma decay. Interestingly we
                      find that the rates of loop-induced decays are correlated
                      and their signal strengths can rise up to $40\%$ - $60\%$
                      depending on the channel. We furthermore study the dark
                      matter phenomenology of the TMSSM. The lightest neutralino
                      is a good dark matter candidate in two regions. The first
                      one is related to the Higgs and Z resonances and the LSP is
                      mostly Bino. The second one is achieved for a mass larger
                      than 90 GeV and the LSP behaves as the well-tempered
                      neutralino. An advantage of the triplet contribution is that
                      the well-tempered neutralino can be a Bino-Triplino mixture,
                      relieving the problem of achieving $M_2$ ~ $M_1$ in unified
                      scenarios. The dark matter constraints strongly affect the
                      Higgs phenomenology, reducing the potential enhancements of
                      the diphoton and of the Z + photon channels by $20\%$ at
                      most. These enhancements are however larger than the MSSM
                      ones. In the near future, complementarity of dark matter
                      direct searches and collider experiments will be crucial to
                      probe most of the parameter space where the neutralino is
                      the dark matter candidate.},
