Model with two global Z2 symmetries

Post by amaliab2 » 10. Aug 2018, 17:42

Dear Florian,

I am trying to implement a model in SARAH where there are two global Z2 symmetries. The new fermionic sector is charged under one of them while the new scalar sector is charged under the other one. I have defined the symmetries as follows:

Global[[1]] = {Z[2], Z2};
Global[[2]] = {Z[2], Z22}

Then, a new fermion field looks like this:
FermionFields[[7]] = {rd, 1, {vd,ed}, -1/2, 2, 1, -1 ,1};

While a new scalar field looks like this:
ScalarFields[[2]] = {Et, 1, {etp, etO}, 1/2, 2, 1, 1, -1};

When I try to implement the model in micrOmegas I only get dark matter from the fermion sector, and in fact in the .mdl files I can see that the scalar sector does not have the convention for being in the odd sector (e.g. ~~). So, I have a few questions:
Is this the correct way to include two new global symmetries?
Is it possible to use micrOmegas with SARAH's CHep files in order to study a model with multicomponent dark matter?

Thank you very much,

Amalia

Hi,

I guess the question is answered here:

It works with the two DM particles.

Thank you very much!
