Potential Issue in RunSM_MSSM

Post by jjonesperez » 5. Aug 2016, 17:53

Hi all,

I have spotted a potential problem in RunSM_MSSM. Let me first summarize what I understand the procedure does.

The procedure runs SUSY and SM parameters from M_SUSY to Q_in. This can be controlled with flags 62 and 63.
With flag 62 = 1, both SUSY and SM parameters run from M_SUSY to Q_in.
With flag 63 = 1, the SM parameters only are taken from MZ, and run to Q_in, overriding the previous running from M_SUSY.

The issue I have spotted would happen if flag 63 = 0. After evaluating flag 62, the procedure rotates all SUSY matrices to the SCKM basis. If flag 63 = 1, the SUSY matrices are rotated back to the EW basis using the mixing from the new Yukawas, and are then given as output. However, if flag 63 = 0, the SUSY matrices are left on the SCKM basis.

To my understanding, this problem would be solved by moving the Switch_to_superCKM subroutine within the IF statement evaluating flag 63.

Cheers!
