Here, <i>P</i> represents the pseudoscalar mesons <span>({pi })</span> and <i>K</i>, while <i>V</i> denotes the ground-state vector mesons. The investigation incorporates two key refinements: the contribution of the subleading-twist WF <span>(phi _{B2})</span> of the <span>(B_s)</span> meson and the effects of higher-order terms in the distribution amplitudes (DAs) of the final-state mesons. We emphasize that <span>(phi _{B2})</span> is not merely a numerical correction, but a necessary ingredient to preserve gauge invariance. Employing the minimum <span>(chi ^2)</span> method, we optimize the shape parameter <span>(omega _{B_s})</span> of the <span>(B_s)</span> meson WF and systematically calculate the branching ratios and CP violation parameters for these decay modes. Our results demonstrate that the inclusion of <span>(phi _{B2})</span> significantly impacts both the branching ratios and CP asymmetries, resulting in better agreement with existing experimental data for specific channels.

While the higher-order corrections in the final-state meson DAs yield comparatively smaller effects, they still enhance the theoretical predictions. These findings highlight the importance of refining both WF modeling and higher-order contributions in pQCD calculations. Future high-precision experimental measurements will further test these predictions, while continued theoretical efforts are essential for exploring additional interaction mechanisms and systematic uncertainties.

Due to the addition of the magnetic charge <span>(tilde{Q}_m)</span>, the study of the phase transition becomes much richer by obtaining a non-equilibrium phase transition from an unstable small black hole to a stable large black hole along with the Van der Waals and superfluid phase transition with an extra unstable branch in the <span>(T-S)</span> processes.

The core of the apparatus is a dual-phase Time Projection Chamber (TPC), filled with 50 tonnes of low radioactivity underground argon (UAr) acting as the WIMP target. NUV-HD-cryo Silicon Photomultipliers (SiPM)s designed by Fondazione Bruno Kessler (FBK) (Trento, Italy) were selected as the photon sensors covering two <span>(10.5~text {m}^2)</span> Optical Planes, one at each end of the TPC, and a total of <span>(5~text {m}^2)</span> photosensitive surface for the liquid argon veto detectors. This paper describes the Quality Assurance and Quality Control (QA/QC) plan and procedures accompanying the production of FBK NUV-HD-cryo SiPM wafers manufactured by LFoundry s.r.l. (Avezzano, AQ, Italy). SiPM characteristics are measured at 77 K at the wafer level with a custom-designed probe station. As of March 2025, 1314 of the 1400 production wafers (94% of the total) for DarkSide-20k were tested. The wafer yield is <span>(93.2pm 2.5)</span>%, which exceeds the 80% specification defined in the original DarkSide-20k production plan. \u0000\u0000\u0000</p></div>","PeriodicalId":788,"journal":{"name":"The European Physical Journal C","volume":"85 5","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1140/epjc/s10052-025-14196-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
