Faddeev and Korepin have stressed that ultraviolet divergences cancel in the soliton sector if they cancel in the vacuum sector when the corresponding calculations are identical in the ultraviolet. We therefore renormalize the divergences in the vacuum sector using a Schrodinger picture prescription, which mirrors closely the analogous calculations in the domain wall sector.</div></div>","PeriodicalId":54712,"journal":{"name":"Nuclear Physics B","volume":"1018 ","pages":"Article 117054"},"PeriodicalIF":2.8,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144749620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

A wave source placed on the AdS boundary yields a response function on the antipodal side, from which a virtual optical system with a convex lens reconstructs the holographic image of the Einstein ring. The analysis systematically explores the impact of physical parameters and observer position on the ring's morphology. As the observer's position varies, the image transitions from a complete ring to an arc and eventually to a single bright point. The Einstein ring radius is observed to decrease with increasing wave frequency <em>ω</em>, and chemical potential <em>μ</em>, while it increases with electric charge <em>e</em> and temperature <em>T</em>. Increasing <em>η</em> reduces the image sharpness. In contrast, the quantum correction parameter <em>a</em> has negligible effect on the ring radius or response amplitude, as its contribution falls off rapidly near the boundary and remains subleading in the wave dynamics. The parameter <em>e</em> enhances the electromagnetic lensing strength, leading to a broader ring. Geometric optics analysis confirms that the incident angle of the photon ring matches the Einstein ring angle, validating consistency across frameworks. Overall, the results highlight how nonlinear electromagnetic effects and bulk field configurations manifest in observable boundary features, providing a means to distinguish quantum-corrected black holes from classical solutions.</div></div>","PeriodicalId":54712,"journal":{"name":"Nuclear Physics B","volume":"1018 ","pages":"Article 117048"},"PeriodicalIF":2.8,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144722511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

It also has the capability of detecting lower energy particles relative to ATLAS and CMS. In this paper, we assess MATHUSLA's potential for effectively probing hidden valley models. As a benchmark, we assume the hidden valley sector communicates with Standard Model sectors via a heavy vector propagator that couples to Standard Model quarks as well as hidden valley quarks.
