\bottomheading{Two jets, scalar mediator, processes 842 and 847}

842~$S\to({\chi}(p_3)+\bar{\chi}(p_4)) +f(p_5)+f(p_6)$ [Scalar Mediator]   LO\\
847~$S\to({\chi}(p_3)+\bar{\chi}(p_4)) +\gamma(p_5)+f(p_6)$ [Scalar Mediator]   LO

Processes 842 and 847 represent the production of DM plus two jets or
DM plus one jet and one photon and are available at LO.
