New constraints on ultraheavy dark matter from the LZ experiment
Searches for dark matter with liquid xenon time projection chamber experiments have traditionally focused on the region of the parameter space that is characteristic of weakly interacting massive particles, ranging from a few <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mrow><a:mi>GeV</a:mi><a:mo>/</a:mo><a:msup><a:mrow><a:mi>c</a:mi></a:mrow><a:mrow><a:mn>2</a:mn></a:mrow></a:msup></a:mrow></a:math> to a few <c:math xmlns:c="http://www.w3.org/1998/Math/MathML" display="inline"><c:mi>TeV</c:mi><c:mo>/</c:mo><c:msup><c:mi>c</c:mi><c:mn>2</c:mn></c:msup></c:math>.
