\bottomheading{Two jets, pseudo scalar mediator, processes 843 and 848}
843~$PS\to({\chi}(p_3)+\bar{\chi}(p_4)) +f(p_5)+f(p_6)$ [Pseudo Scalar Mediator]   LO \\
848~$PS\to({\chi}(p_3)+\bar{\chi}(p_4)) +\gamma(p_5)+f(p_6)$ [Pseudo Scalar Mediator]   LO

Processes 843 and 848 represent the production of DM plus two jets or
DM plus one jet and one photon and are available at LO.
