Establishing such a calibration pipeline motivates the present work. Within this context, diquark correlations [58-60] provide a robust, quantitatively testable description of baryon structure and serve as a natural bridge between conventional and exotic hadrons [61-65]. Recent CMS limits on quark substructure down to 10 −20 m [66] preclude spatial smearing at TeV scales, justifying the contact-interaction limit in our chromomagnetic interaction and reinforcing the treatment of the diquark as a dynamically compact cluster. This interpreta- tion is further supported by flavor-decomposition analyses of nucleon electromagnetic form factors at high momentum transfers [58, 67]. Additional evidence comes from heavy-baryon production"},{"citing_arxiv_id":"2602.19504","ref_index":19,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Three-body molecular states composed of $D^{(*)}$ and two nucleons","primary_cat":"hep-ph","submitted_at":"2026-02-23T04:40:54+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":4.0,"formal_verification":"none","one_line_summary":"The DNN system forms a robust compact bound state in the I=1/2 (1^-) channel across cutoffs, while D*NN exhibits spin-dependent bound states in 0^-, 1^-, and 2^- channels with no resonances found.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"2602.18075","ref_index":43,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Hidden-charm $uds\\,c\\bar c$ pentaquarks as flavor eigenstates in a constituent quark model","primary_cat":"hep-ph","submitted_at":"2026-02-20T08:59:11+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":5.0,"formal_verification":"none","one_line_summary":"Imposing the SU(3) flavor eigenstate condition on udsc c-bar pentaquarks in a constituent quark model yields two structures matching the masses of P_cs(4338) and P_cs(4459) plus two additional predicted states below the J/ψΛ threshold.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"2602.08811","ref_index":13,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Assessing the validity of the Born-Oppenheimer approximation in potential models for doubly heavy hadrons","primary_cat":"hep-ph","submitted_at":"2026-02-09T15:49:11+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":5.0,"formal_verification":"none","one_line_summary":"Born-Oppenheimer approximation calculations for doubly heavy hadrons match Gaussian expansion benchmarks at small heavy quark masses but diverge at larger masses, with Slater-type functions overestimating and Gaussian-type underestimating binding energies.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"2511.20428","ref_index":4,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Observation and investigation of the $T_{c\\bar{c}1}(4430)^{+}$ structure in $B^{+} \\to \\psi(2S) K_{\\text{S}}^{0} \\pi^{+}$ decays","primary_cat":"hep-ex","submitted_at":"2025-11-25T15:56:22+00:00","verdict":"ACCEPT","verdict_confidence":"MODERATE","novelty_score":5.0,"formal_verification":"none","one_line_summary":"First 4D amplitude analysis of B+ → ψ(2S) K_S0 π+ confirms the exotic T_{c c-bar 1}(4430)+ structure with properties consistent with prior observations in the isospin-related channel.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"2503.03555","ref_index":21,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Analysis of molecular state ${{\\eta}_cD^*}$ and ${J/\\psi D^*}$ in the effective Lagrangian approach","primary_cat":"hep-ph","submitted_at":"2025-03-05T14:42:56+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":3.0,"formal_verification":"none","one_line_summary":"Using effective Lagrangians under molecular assumptions for η_c D* and J/ψ D*, the authors estimate B_c production branching ratios of 10^{-4} and 10^{-5} respectively, with decay widths O(MeV).","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"2503.00552","ref_index":1,"ref_count":1,"confidence":0.98,"is_internal_anchor":true,"paper_title":"Study of $1^{--}$ P wave charmoniumlike and bottomoniumlike tetraquark spectroscopy","primary_cat":"hep-ph","submitted_at":"2025-03-01T16:38:04+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":3.0,"formal_verification":"none","one_line_summary":"Constituent quark model with imported meson parameters predicts lowest 1-- P-wave tetraquark mass near 4.15 GeV and proposes that ψ(4230), ψ(4360), ψ(4660), and Υ(10753) may be such states with possible multiples near 4.36 GeV.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null}],"limit":50,"offset":0}
