Goal (ambitious): study the interplay between RD anomalies and Dark Matter.

Goal (concrete): use the S1 leptoquark model that solves RD and RD* and study the dark matter aspect.

Tasks:

1- Get a working Lagragian. From private communication with D. Marzocca we need to have both left handed and right handed couplings to S1. Doublet coupling is needed for bL vL, but singlet coupling is fine for cR-tauR. We need a 3rd coupling (y) to chi1-chi0. Persons in charge: Benjamin, Dipan.

2- RD explained by mS1=2 TeV, and both lq couplings being 1. (From D. Marzocca). Anomaly explained by lambda_bv * lambda_ctau / mS1^2.

3- Study bounds from direct detection. These happen at the 1-loop level, expressions known in literature for the SUSY case. In charge: Genevieve, Andreas, Dipan, Jose Miguel.

4- look into CMS search for LQ + MET (motivated by the “Coannihilation Codex”) and for existing searches constraining chi1. In charge: Aoife, José.

5- study relic density (after 1-4 are done). Jan
