Signal Diversity and EFT in Dark Matter Direct Detection Bradley J Kavanagh GRAPPA, University of Amsterdam 25th June 2018, DSU, Annecy b.j.kavanagh@uva.nl @BradleyKavanagh
Last time I was in Annecy was January 2016… … and everyone in the audience looked a little sleep deprived…
Anyway, now we have the XENON1T 1-sigma excess… * @pjtunney * or rather, theorists… 3 Bradley J. Kavanagh (GRAPPA, Amsterdam) Effective Field Theory in Direct Detection

Kavanagh (GRAPPA, Amsterdam) Effective Field Theory in Direct Detection
Non-standard interactions? Why? Out of curiosity • Don’t you just want to know…? What could DM look like? What could we be missing? Input for experimental analysis • Experimental searches are not simple cut-and-counts - need to know what the signal looks like to get the best sensitivity Optimisation of future experiments • Which experiments should we use to get the best sensitivity, or the most information out of a future detection? (more on this later) 5 Bradley J. Kavanagh (GRAPPA, Amsterdam) Effective Field Theory in Direct Detection
Experimental analysis Limits depend on a signal hypothesis and we need to know where to look! [1805.12562] So where should we look? [1705.02614] 6 Bradley J. Kavanagh (GRAPPA, Amsterdam) Effective Field Theory in Direct Detection
