We find that temperature dependence of the zero-range parameters can vary from one set of measurements to another as it may be driven by the distribution of error bars in the experiment, and not by the underlying three-body physics. To study finite-temperature effects in three-body recombination beyond the zero-range physics, we introduce and examine a finite-range model based upon a hyperspherical formalism. The systematic error discussed in this Letter may provide a significant contribution to the error bars of measured three-body parameters.","lang":"eng"}],"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2302.01022","open_access":"1"}],"department":[{"_id":"MiLe"},{"_id":"OnHo"}],"issue":"6","publication_status":"published","date_published":"2023-06-20T00:00:00Z","year":"2023","volume":107,"intvolume":"       107","project":[{"call_identifier":"H2020","grant_number":"801770","name":"Angulon: physics and applications of a new quasiparticle","_id":"2688CF98-B435-11E9-9278-68D0E5697425"}],"acknowledgement":"We thank Jan Arlt, Hans-Werner Hammer, and Karsten Riisager for useful discussions.
