First constraints on WIMP-nucleon effective field theory couplings in an extended energy region from LUX-ZEPLIN
First constraints on WIMP-nucleon effective field theory couplings in an extended energy region from LUX-ZEPLIN
Following the first science results of the LUX-ZEPLIN (LZ) experiment, a dual-phase xenon time projection chamber operating from the Sanford Underground Research Facility in Lead, South Dakota, USA, we report the initial limits on a model-independent nonrelativistic effective field theory describing the complete set of possible interactions of a weakly …
