Measurements and models of enhanced recombination following inner-shell vacancies in liquid xenon Open
Electron-capture decays of Xe 125 and Xe 127 , and double-electron-capture decays of Xe 124 , are backgrounds in searches for weakly interacting massive particles (WIMPs) conducted by dual-phase xenon ti…

First constraints on WIMP-nucleon effective field theory couplings in an extended energy region from LUX-ZEPLIN Open
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-…

Performance of the CMS High Granularity Calorimeter prototype to charged pion beams of 20–300 GeV/c Open
The upgrade of the CMS experiment for the high luminosity operation of the LHC comprises the replacement of the current endcap calorimeter by a high granularity sampling calorimeter (HGCAL). The electromagnetic section of the HGCAL is base…

A search for new physics in low-energy electron recoils from the first LZ exposure Open
The LUX-ZEPLIN (LZ) experiment is a dark matter detector centered on a dual-phase xenon time projection chamber. We report searches for new physics appearing through few-keV-scale electron recoils, using the experiment's first exposure of …

Background determination for the LUX-ZEPLIN dark matter experiment Open
The LUX-ZEPLIN experiment recently reported limits on WIMP-nucleus interactions from its initial science run, down to 9.2 x 10–48 cm2 for the spin-independent interaction of a 36 GeV/c2 WIMP at 90% confidence level. In this paper, we prese…

Construction and commissioning of CMS CE prototype silicon modules Open
As part of its HL-LHC upgrade program, the CMS Collaboration is developing a High Granularity Calorimeter (CE) to replace the existing endcap calorimeters. The CE is a sampling calorimeter with unprecedented transverse and longitudinal rea…
View article: Use and reuse of SMEFT
Use and reuse of SMEFT Open
In this work we address three questions: can we successfully describe (observed) deviations from the standard model in the SMEFT language? Can we learn something about the underlying, beyond the standard model, physics using the SMEFT lang…
