Collider observations have mainly been studied on an event-by-event basis,
leveraging several kinematic techniques. However, the intrinsic topological
imprints of the ensemble of new physics events can be strikingly different from
the SM background ensemble. Traditional topological data analysis (TDA) is
known for its stability against small perturbations. However, a plethora of
rich information encoded in the clustering of ensembles is often lost due to
the unweighted filtration of simplicial complexes. Taking a singlet extended
model as an example, this work illustrates the rich global properties
associated with the so-called distance-to-measure (DTM) filtration on Alpha
complexes using weights determined from k-nearest neighbours.Comment: 1 table, 7 figure
