“…Recently, some of us have analysed various phenomenological aspects of F-theory effective models using the spectral cover description [15,16,17]. While, in F-constructions, R-parity conservation (RPC) can emerge either as a remnant symmetry of extra U (1) factors, or it can be imposed by appealing to some geometric property of the internal manifold and the flux [18], there is no compelling reason to assume this.…”

We discuss R-parity violation (RPV) in semi-local and local F-theory constructions. We first present a detailed analysis of all possible combinations of RPV operators arising from semi-local F-theory spectral cover constructions, assuming an SU(5) GUT. We provide a classification of all possible allowed combinations of RPV operators originating from operators of the form 10 ·5 ·5, including the effect of U(1) fluxes with global restrictions. We then relax the global constraints and perform explicit computations of the bottom/tau and RPV Yukawa couplings, at an SO(12) local point of enhancement in the presence of general fluxes subject only to local flux restrictions. We compare our results to the experimental limits on each allowed RPV operator, and show that operators such as LLe c , LQd c and u c d c d c may be present separately within current bounds, possibly on the edge of observability, suggesting lepton number violation or neutron-antineutron oscillations could constrain F-theory models.

“…More precisely, the tree-level operators : The effect of these terms strongly depend on the dynamics of the singlets, however it would be desirable to completely eliminate such operators. One can impose an R-symmetry by hand [47] or to investigate the geometric origin of discrete Z N symmetries that can eliminate such operators [55][56][57][58]. In addition, the study of such Yukawa coefficients at a local-level, shows that they can be suppressed for wide regions of the flux parameter space [59].…”

On the LHC signatures of $$SU(5)\times U(1)'$$ F-theory motivated models

We study low energy implications of F-theory GUT models based on SU(5) extended by a $$U(1)'$$ U ( 1 ) ′ symmetry which couples non-universally to the three families of quarks and leptons. This gauge group arises naturally from the maximal exceptional gauge symmetry of an elliptically fibred internal space, at a single point of enhancement, $$E_8\supset SU(5)\times SU(5)'\supset SU(5)\times U(1)^4.$$ E 8 ⊃ S U ( 5 ) × S U ( 5 ) ′ ⊃ S U ( 5 ) × U ( 1 ) 4 . Rank-one fermion mass textures and a tree-level top quark coupling are guaranteed by imposing a $$Z_2$$ Z 2 monodromy group which identifies two abelian factors of the above breaking sequence. The $$U(1)'$$ U ( 1 ) ′ factor of the gauge symmetry is an anomaly free linear combination of the three remaining abelian symmetries left over by $$Z_2$$ Z 2 . Several classes of models are obtained, distinguished with respect to the $$U(1)'$$ U ( 1 ) ′ charges of the representations, and possible extra zero modes coming in vector-like representations. The predictions of these models are investigated and are compared with the LHC results and other related experiments. Particular cases interpreting the B-meson anomalies observed in LHCb and BaBar experiments are also discussed.

“…Clearly, to avoid decoupling of the Higgs doublets from the light spectrum, we must assume that θ 13 is very small and close to the TeV scale. Regarding RPV terms these can be controlled by imposing certain discrete symmetries of geometric origin [23,24,25] or by considering local Yukawa flux effects as described in [26].…”

We discuss low energy implications of F-theory GUTs based on SU(5) extended by a U(1)' symmetry which couples non-universally to the three chiral families. Several classes of anomaly free models are obtained, distinguished with respect to the U(1)' charges of the representations, and possible extra zero modes coming in vector-like pairs. We considered the case where the spontaneous breaking of the U(1)' symmetry occurs at a few TeV scale and we compute the observables of several flavor violation exotic processes in the effective theory. Particular cases interpreting the B-meson anomalies observed in LHCb experiments are also discussed.
