Mellouki","doi":"10.1103/qcx4-9x8t","DOIUrl":"https://doi.org/10.1103/qcx4-9x8t","url":null,"abstract":"Recent results from the DAMIC-M and PandaX collaborations have excluded the standard freeze-in production of dark matter for masses in the range 3     MeV ≲ m χ ≲ 1     GeV in the context of extensions of the Standard Model featuring an additional ultralight U ( 1 ) X gauge boson. In this work, we analyze the constraints induced by DAMIC-M and PandaX results on the reheating temperature in freeze-in models at stronger coupling, or when a nonthermal source (such as inflaton decay) comes into play. We identify viable scenarios in which the DM relic abundance is correctly reproduced while evading current experimental bounds on the electron-scattering cross section, σ ¯ e . In particular, we show that for reheating temperatures below the electroweak scale, Boltzmann-suppressed production can be compensated by stronger couplings, bringing freeze-in scenarios within present experimental reach. Finally, we study a hybrid scenario in which a small branching ratio of inflaton decay seeds a nonzero initial dark-matter abundance. We show that such contributions can significantly modify freeze-in predictions across broad regions of parameter space, offering an additional pathway for probing extremely feeble interactions.","PeriodicalId":20167,"journal":{"name":"Physical Review D","volume":"8 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149150447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the generalized Liouvillian L = κ 1 ( L 1 + L − 1 ) + κ 2 ( W 2 + W − 2 ) , we compute the Lanczos coefficients in the descendant module of a heavy primary and find several classes with faster-than-linear growth in the descendant level N , including maximally violating sectors with asymptotic behavior b N ∼ N 2 . This superlinear growth exceeds the conjectured bound and renders the Krylov complexity divergent. We further show that the same quadratic asymptotic growth already arises in the global S L ( 3 , R ) subalgebra, indicating that the violation is rooted in the extended higher-rank symmetry itself. Our results demonstrate that extended W symmetries can qualitatively modify operator growth and evade conventional bounds on information scrambling.","PeriodicalId":20167,"journal":{"name":"Physical Review D","volume":"42 1","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149150452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
