DESCRIPTION:Speakers: Izabela Anna Kochanek (Istituto Nazionale di Fisica 
 Nucleare)\, Nicola Rossi (Istituto Nazionale di Fisica Nucleare)\, Dounia 
 Helis (Istituto Nazionale di Fisica Nucleare)\, Valerio D'Andrea (Istituto
  Nazionale di Fisica Nucleare)\n\nParity-conjugated copies of standard mod
 el particles\, so-called mirror particles\, could provide answers for seve
 ral standing issues in physics\, and in particular they can be viable cand
 idates for dark matter. The ordinary neutral particles (e.g. neutrinos or 
 the neutron) can have mixing with their mirror twins\, with interesting ph
 enomenological and astrophysical implications. Our experiment at the Paul 
 Scherrer Institute (PSI) was designed to search for anomalous disappearanc
 e of ultracold neutrons (UCN) that could hint towards neutron-to-mirror-ne
 utron oscillations. The experiment was conducted in a controlled magnetic 
 field\, scanning from 5 muT to 100 muT. I provide an overview of the exper
 iment\, its data analysis based on Monte Carlo simulations and precise mag
 netic field maps\, and present new limits on the oscillation time.--------
