In particular, I have tried creating the model files including the SARAH model files for the MSSM with bilinear RpV [<span><a href="https://arxiv.org/abs/hep-ph/9906310" target="_blank">arXiv:hep-ph/9906310</a>] </span>and similarly for NMSSM with bilinear RpV [<span><a href="https://arxiv.org/abs/hep-ph/0604216" target="_blank">arXiv:hep-ph/0604216</a>]. <br></span></div><div><span><br></span></div><div><span>For the MSSM-BiRpV model, I initially had an issue with FlexibleSUSY not being able to solve the tree level tadpole equations for the EWSBOutputParameters so I tried manually giving the solutions through the variable "TreeLevelEWSBSolutions" (see the <a href="http://FlexibleSUSY.m.in" target="_blank">FlexibleSUSY.m.in</a> file attachment). However, I get the following error upon compiling the code:<br></span><img src="cid:ii_l8tyia7p1" alt="image.png" width="558" height="151"><br></div><div>Would you be able to clarify the error statement?<br></div><div><span></span></div><div>"Parameters given in TreeLevelEWSBSolution, do not match<br> the Parameters given in FlexibleSUSY`EWSBOutputParameters!"</div><div><br></div><div>Here are the said Parameters mentioned in the error statement:<br><img src="cid:ii_l8tym1hn2" alt="image.png" style="margin-right:0px" width="403" height="46"><br><img src="cid:ii_l8tyn3tr3" alt="image.png" width="558" height="530"><br></div><div><br></div><div>My guess is that FlexibleSUSY is not able to recognize the indexed parameters mlHd2[0], mlHd2[1], and mlHd2[3] (perhaps the notation?). In line with this, I would like to ask the following questions:<br>1. What is the correct way of specifying these parameters given that there has to be 5 entries provided, following the 5 EWSB Tadpole equations (1 for vu, 1 for vd, and 3 for vL where vL are three sneutrino vevs)?</div><div>2. Are these issues perhaps due to the RpV nature of the model having 3 generations of sneutrino vevs? <br></div><div>3. What are the limitations of FlexibleSUSY in handling R-parity violating SUSY models?<br></div><div><br></div><div>I would really appreciate it if you can help me out since I plan to use this tool for my PhD Dissertation. I realize there are other tools I can use like SOFTSUSY and SPheno together with SARAH and I am also currently exploring these tools as well. However, I would very much like to explore further using FlexibleSUSY given its advantages over these other spectrum calculators. Your github page has been a really great help and I wish you all the best in your future projects. <br></div><div><br></div><div>I have attached the FlexibleSUSY model file I used and the default SARAH model files for MSSM-BiRpV that came together with version 4.14.5. The setup and software version I am using is as follows: <br>Ubuntu-22.04.1 LTS</div><div>Mathematica-12.3.0<br></div><div>SARAH-4.14.5</div><div>FlexibleSUSY-2.7.1</div><div><br></div><div>Thank you very much.</div></div></div></div>
