Proposal for generalised Supersymmetry Les Houches Accord for see-saw models and PDG numbering scheme

Understand

The SUSY Les Houches Accord (SLHA) 2 extended the first SLHA to include various generalisations of the Minimal Supersymmetric Standard Model (MSSM) as well as its simplest next-to-minimal version.

• Here, we propose further extensions to it, to include the most general and well-established see-saw descriptions (types I/II/III, inverse, and linear) in both an effective and a simple gauged extension of the MSSM framework.
• In addition, we generalise the PDG numbering scheme to reflect the properties of the particles.
