In this paper, we explore motions of spinning particles orbiting a Reissner-Nordström black hole and examine whether this bound is violated in the spinor field of this black hole. For the neutral particle, when its spin magnitude surpasses a specific threshold, the value of the exponent exceeds the surface gravity, resulting in a violation of the bound. Given a fixed total angular momentum of the particle, when its spin direction is anti-aligned with the angular momentum direction, the exponent value is greater than that when the two directions are aligned. For the charged particle, taking into account the influence of the electromagnetic force, we find that for relatively large angular momenta, although the electromagnetic force does not change the trend of the exponent’s variation with respect to spin and angular momentum, and only modifies its values, it still leads to the violation. Therefore, the chaos bound violations are observed in the spinor field.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2026 4","pages":""},"PeriodicalIF":5.5,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP04(2026)205.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147738562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

A new ingredient in this work is the requirement that the observed baryon asymmetry is explained via non-thermal leptogenesis, which can be realized in a large class of supersymmetric hybrid inflation models including SO(10). We provide estimates for the masses of the three Standard Model neutrinos (with the lightest mass m1 ≈ 5 meV) as well as the three right-handed neutrinos (M1 ≈ 109 GeV and M2,3 ≈ 1013 GeV). The best fit estimate for the leptonic CP violating parameter δPMNS ≈ 235°, and the value of the neutrinoless double beta decay mass parameter mββ ≈ 0.18 meV. A numerical analysis broadens the predicted range for δPMNS (100°–300°), but leaves largely intact the predictions for the six (light and heavy) neutrino masses and mββ. Our statistical analysis, which yields the likelihood-predicted ranges of the observables, is fully consistent with JUNO’s newly released first measurement of reactor neutrino oscillations in the ( Delta {m}_{12}^2 )-sin2 θ12 plane, with JUNO improving the precision by a factor of 1.6 relative to the combination of all previous measurements. The implementation of successful non-thermal leptogenesis allows us to provide estimates for the inflaton mass (mχ ≈ 7 × 109 GeV) and the reheating temperature (TRH ≈ 4 × 106 GeV).","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2026 4","pages":""},"PeriodicalIF":5.5,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP04(2026)204.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147738855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Our construction interpolates between the 1/2-BPS D3-D3 system and its field theory dual at one end, and the holographic duality presented in [1] at the other. On the gravity side, the defect is realised by a novel D5 probe brane embedded in the AdS5 × S5 geometry. The symmetry of the induced on the D5 brane metric is AdS3 × S1 × S2. At a certain limit the D5 brane becomes singular and resembles the D3-D3 system. Consistency requires the presence of two D7 branes on which the D5 brane terminates. The existence of boundaries induces a gauge anomaly for the D5 brane which is cancelled through anomaly inflow from the D7 branes. The full system of the D5 and D7 branes is, thus, anomaly free. Also it does not have any tachyonic instabilities for a certain range of its parameters. On the field theory side, we determined the classical solution of the ( mathcal{N} ) = 4 SYM equations of motion which we conjecture to describe the defect dual to the D5-D7 system and comment on the identification of the parameters appearing at the two sides of the duality.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2026 4","pages":""},"PeriodicalIF":5.5,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP04(2026)201.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147738856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

We employ tensor network methods to study such dynamics using interacting scalar and gauge theories in 1+1 spacetime dimensions, subject to a quench modeling a homogeneously expanding gravitational background. The models considered are the scalar λϕ4 theory and the Schwinger model, i.e. a Dirac fermion coupled to a U(1) gauge field which is equivalent via bosonization to a scalar field with a cosine self-interaction. In the free scalar limit, both theories reproduce known analytical results, providing a nontrivial numerical validation of bosonization in curved spacetime for the Schwinger model. Our central finding is that self-interactions lead to a suppression of gravitational particle production compared to the free-field case, as evidenced by two-point functions and the spectra of produced particles. We further examine the behavior of entanglement generation and find that interactions suppress entanglement growth in the λϕ4 theory, while in the Schwinger model, the interplay between suppressed particle production and enhanced inter-particle correlations leads to more complex entanglement behavior. Our results pave the way for further explorations of nonperturbative quantum real-time dynamics of interacting scalar and gauge theories in arbitrary gravitational backgrounds.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2026 4","pages":""},"PeriodicalIF":5.5,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP04(2026)183.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147796401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Effective Polyakov loop theories derived from lattice QCD via combined strong-coupling and hopping expansions are valid for heavy quarks only, but tractable with a significantly less severe sign problem. In this work, we apply three mean-field approximations to these effective theories, each incorporating local fluctuations to different degrees. We compare their predictions against Monte Carlo results for the deconfinement transition at high temperatures and for the baryon onset transition at low temperatures. In agreement with earlier effective theory simulations, we find a first-order nuclear liquid-gas transition with a critical end point for very low temperatures and moderately heavy quarks. While the location of fluctuation-dominated critical end points is expectedly inaccurate, the phase diagram of lattice QCD with heavy quarks can be determined qualitatively with entirely analytical methods.","PeriodicalId":635,"journal":{"name":"Journal of High Energy Physics","volume":"2026 4","pages":""},"PeriodicalIF":5.5,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/JHEP04(2026)189.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147738705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
