Error: Dimension of ZH does not fit to defined dependence

Post by giorgiobusoni » 16. Jun 2016, 12:35

I am trying to implement a modified version of a THDM-III. I started by duplicating the THDM-III model and editing it, adding the additional fields I wanted. In particular, there will now be 3 scalars in the model.
When I load the model, I get:

Dimension of ZH does not fit to defined dependence

Where ZH is the matrix used to diagonalise the mass matrix of the scalars, defined in MatterRotations

DEFINITION[EWSB][MatterSector]=
{ {{phi1, phi2, phi3}, {hhh, ZHS}},
....

I don't understand why this error is coming from, as I cannot set the dimension of the matrix ZH anywhere, as far as i understood

Hi,

this is for instance explained here: 1503.04200, page 45. You need to set

Code: Select all

{ ZH , { Description - > "Scalar-Mixing-Matrix" ,
DependenceOptional - > None }} ,
{ ZA , { Description - > "Pseudo-Scalar-Mixing-Matrix" ,
DependenceOptional - > None }} ,
in particles.m

Cheers,
Florian

ok, thanks. So without these options Sarah uses the default matrix, that is dimension 2, right?

I noticed that in check model the following warnings come out:
"The first two levels of {} cannot be transposed."
not only in my defined model, but also in models in the database, like SM. Is it normal?

That message shouldn't cause any problem.
