Nevertheless, the SM is unable to account for numerous observations. In particular, multiple cosmological measurements point towards the existence of dark matter (DM) [1], the abundance of which is predicted to significantly outweigh that of normal matter. Although the specific nature of DM remains unknown, one of the most widely supported scenarios is that DM takes the form of a weakly interacting, long-lived massive particle [1, 2]. The SM, however, contains no such particle. Assuming that DM is a particle that can interact with normal matter, it might be possible to detect it experimentally."},{"citing_arxiv_id":"2605.09381","ref_index":68,"ref_count":1,"confidence":0.88,"is_internal_anchor":false,"paper_title":"Probing the nature of $D_1 K$ and $D_2 K$ molecules through $D_s^{(*)}\\pi\\pi$ and $D_{s0(s1)}\\pi$ decays","primary_cat":"hep-ph","submitted_at":"2026-05-10T07:12:23+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":5.0,"formal_verification":"none","one_line_summary":"Theoretical predictions show narrow peaks near DK and D*K thresholds in Ds pi and Ds* pi spectra plus large partial widths for isospin-violating decays of D1K and D2K molecular states.","context_count":1,"top_context_role":"background","top_context_polarity":"background","context_text":"1103/PhysRevLett.113.162001 [arXiv:1407.7574 [hep- ex]].
