Signatures of few-body resonances in finite volume
P. Klos, S. König, H. -W. Hammer +2
We study systems of bosons and fermions in finite periodic boxes and show how the existence and properties of few-body resonances can be extracted from studying the volume dependen…
Discriminating WIMP-nucleus response functions in present and future XENON-like direct detection experiments
A. Fieguth, M. Hoferichter, P. Klos +3
The standard interpretation of direct-detection limits on dark matter involves particular assumptions of the underlying WIMP-nucleus interaction, such as, in the simplest case, the…
Quantum Monte Carlo calculations of two neutrons in finite volume
P. Klos, J. E. Lynn, I. Tews +5
Ab initio calculations provide direct access to the properties of pure neutron systems that are challenging to study experimentally. In addition to their importance for fundamental…
Is a Trineutron Resonance Lower in Energy than a Tetraneutron Resonance?
S. Gandolfi, H. -W. Hammer, P. Klos +2
We present quantum Monte Carlo calculations of few-neutron systems confined in external potentials based on local chiral interactions at next-to-next-to-leading order in chiral eff…
First results on the scalar WIMP-pion coupling, using the XENON1T experiment
E. Aprile, J. Aalbers, F. Agostini +128
We present first results on the scalar WIMP-pion coupling from 1 tyr of exposure with the XENON1T experiment. This interaction is generated when the WIMP couples to a virtu…
Uncertainties in constraining low-energy constants from H decay
P. Klos, A. Carbone, K. Hebeler +2
We discuss the uncertainties in constraining low-energy constants of chiral effective field theory from H decay. The half-life is very precisely known, so that the Gamow-T…
Large-scale nuclear structure calculations for spin-dependent WIMP scattering with chiral effective field theory currents
P. Klos, J. Menéndez, D. Gazit +1
We perform state-of-the-art large-scale shell-model calculations of the structure factors for elastic spin-dependent WIMP scattering off 129,131Xe, 127I, 73Ge, 19F, 23Na, 27Al, and…
Signatures of Dark Matter Scattering Inelastically Off Nuclei
L. Baudis, G. Kessler, P. Klos +4
Direct dark matter detection focuses on elastic scattering of dark matter particles off nuclei. In this study, we explore inelastic scattering where the nucleus is excited to a low…
Nuclear structure aspects of spin-independent WIMP scattering off xenon
L. Vietze, P. Klos, J. Menéndez +2
We study the structure factors for spin-independent WIMP scattering off xenon based on state-of-the-art large-scale shell-model calculations, which are shown to yield a good spectr…
