Three-family particle physics models from global F-theory compactificationsCvetič, Mirjam (Avtor) Klevers, Denis (Avtor) Pena, Damian Kaloni Mayorga (Avtor) Oehlmann, Paul (Avtor) Reuter, Jonas (Avtor) black holessupergravitystring theoryconformal field modelsstring dualityWe construct four-dimensional, globally consistent F-theory models with three chiral generations, whose gauge group and matter representations coincide with those of the Minimal Supersymmetric Standard Model, the Pati-Salam Model and the Trinification Model. These models result from compactification on toric hypersurface fibrations X with the choice of base P-3. We observe that the F-theory conditions on the G(4)-flux restrict the number of families to be at least three. We comment on the phenomenology of the models, and for Pati-Salam and Trinification models discuss the Higgsing to the Standard Model. A central point of this work is the construction of globally consistent G(4)-flux. For this purpose we compute the vertical cohomology H-V((2,2)) (X) in each case and solve the conditions imposed by matching the M- and F-theoretical 3D Chern-Simons terms. We explicitly check that the expressions found for the G(4)-flux allow for a cancellation of D3-brane tadpoles. We also use the integrality of 3D Chern-Simons terms to ensure that our G(4)-flux solutions are adequately quantized.20152017-06-27 13:16:42Znanstveno delo66469ISSN: 1029-8479UDK: 530.122.3OceCobissID: 1314148COBISS_ID: 86139137DOI: 10.1007/JHEP08(2015)087ISSN pri članku: 1029-8479NUK URN: URN:SI:UM:DK:00VUQHSIsl
