Incorrect P(B11,3alpha) Cross Sections

Geant4 Version: 11.3.2
Operating System: Sequoia 15.4.1


I am looking to recreate the following plot of P(B11,3alpha) cross sections vs proton energy (which comes from this 2016 study):

I have attempted using the Hadr03 example to test the various PhysicsLists but have not found any that accurately recreate this curve. I see from this previous post that the P(B11,3alpha) cross section is a known problem, however it sounded like an improvement would be added to v11.3 that I am not currently seeing. Therefore I am wondering if there is any update on these cross sections, or if there is anything I can do to try to implement them by hand?

Thanks!
