# Missing processes for indirect detection

Hi,

I am using MadDM for studying relic abundance and indirect detection.

In my model, there are three CP-even neutral Higgs bosons (h1, h2, h3), one CP-odd neutral Higgs boson (ha), and a pair of charged Higgs bosons (hp, hm).

I find that the directory matrix_elements/ contains the following fortran codes for 16 annihilation processes related to relic abundance:

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

matrix_

On the other hand, the directory Indirect/

P1995_chichi_bbx/

P1995_chichi_h1h1/

P1995_chichi_h2h2/

P1995_chichi_h2h3/

P1995_chichi_h3h3/

P1995_chichi_haha/

P1995_chichi_hphm/

P1995_chichi_

P1995_chichi_ttx/

P1995_chichi_wpwm/

P1995_chichi_zz/

Thus, it seems that 5 annihilation processes are missing when calculating indirect detection. They are

chichi_h1h2

chichi_h1h3

chichi_hpwm

chichi_wphm

chichi_zha

I have also noticed that when generate the processes for indirect detection, h1 is identified as an SM particle, while h2, h3, ha, hp, hm are identified as BSM particles. Then the generated annihilation processes contain either two SM particles or two BSM particles in the final state. The final states in the above missing processes contain one SM particle and one BSM particle. I think they have been somehow neglected.

Thanks!

Best regards,

Zhao-Huan
