Reviving minimal left-right supersymmetry in the light of LHC data — Adam Alloul¹, Lorenzo Basso^2,3, Benjamin Fuks^2,4, •Manuel E. Krauss⁵, and Werner Porod⁵ — ¹IUT Colmar, France — ²Université de Strasbourg, France — ³Universität Freiburg, Germany — ⁴CERN, Geneva, Switzerland — ⁵Universität Würzburg, Germany

We investigate a supersymmetric left-right model based on the gauge group SU(3)_c × SU(2)_L × SU(2)_R × U(1)_B−L in which the Higgs sector consists of bidoublets, triplets and a singlet under the two SU(2) groups. It is minimal in the sense that R-parity is conserved. New resonances are expected from the extra gauge bosons Z_R and W_R due to the enlarged gauge sector. We show how the experimental bounds on the W_R are affected by open additional decay channels into supersymmetric particles. Moreover, right-handed neutrinos can easily escape current searches due to the presence of a possibly light charged Higgs boson.
