The Drift by Sanford Lab where our
researchers answer your giant science
questions in bite-sized videos. Submit

the detector like LZ, we collect a huge
amount of data, most of which were really
not that interested in. So this means we
have to develop what we call "analysis
cuts" and these are selections on the data
that remove non-dark matter like events. So an example would be cutting away
every event that has a signal in both
the main detector and one of the vetoes
or cutting away events that have an
energy outside of the range that we
expect dark matter. We have to make sure
these cuts do not remove any actual dark
matter signal and to do this we do
something called "salting the data" and
salt is basically a selection of fake
signal events so it's fake events that
look just like real dark matter that are
injected into the data stream and we
keep it secret from our analyzers which
events are real and which ones are fake
so they go ahead and apply all the cuts
to the data end up with a final dataset
and then we can do the reveal of
removing the the salt and leaving only
the true data behind. And that's when
we'll hope to see a dark matter signal.
