Discrete gauge groups in F-theory models on genus-one fibered Calabi-Yau 4-folds without section [PDF]
, 2016 A bstractWe determine the discrete gauge symmetries that arise in F-theory compactifications on examples of genus-one fibered Calabi-Yau 4-folds without a section.

Three-index symmetric matter representations of SU(2) in F-theory from non-Tate form Weierstrass models [PDF]
Journal of High Energy Physics, 2016 We give an explicit construction of a class of F-theory models with matter in the three-index symmetric (4) representation of SU(2). This matter is realized at codimen-sion two loci in the F-theory base where the divisor carrying the gauge group is ...

Rational F-Theory GUTs without exotics [PDF]
, 2014 We construct F-theory GUT models without exotic matter, leading to the MSSM matter spectrum with potential singlet extensions. The interplay of engineering explicit geometric setups, absence of four-dimensional anomalies, and realistic phenomenology of ...

Heterotic T-fects, 6D SCFTs, and F-theory [PDF]
, 2016 A bstractWe study the (1, 0) six-dimensional SCFTs living on defects of non-geometric heterotic backgrounds (T-fects) preserving a E7 × E8 subgroup of E8 × E8. These configurations can be dualized explicitly to F-theory on elliptic K3-fibered non-compact

Discrete symmetries in Heterotic/F-theory duality and mirror symmetry [PDF]
Journal of High Energy Physics, 2016 We study aspects of Heterotic/F-theory duality for compactifications with Abelian discrete gauge symmetries. We consider F-theory compactifications on genus-one fibered Calabi-Yau manifolds with n-sections, associated with the Tate-Shafarevich group ℤn ...

Type IIB Flux Vacua from M-theory via F-theory [PDF]
JHEP 0903:122,2009, 2008 We study in detail some aspects of duality between type IIB and M-theory. We focus on the duality between type IIB string theory on K3 x T^2/Z_2 orientifold and M-theory on K3 x K3, in the F-theory limit. We give the explicit map between the fields and in particular between the moduli of compactification, studying their behavior under the F-theory ...

Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
FEBS Letters, EarlyView.Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Horizon thermodynamics in f(R) theory
European Physical Journal C: Particles and Fields, 2018 We investigate whether the new horizon first law proposed recently still work in f(R) theory. We identify the entropy and the energy of black hole as quantities proportional to the corresponding value of integration, supported by the fact that the new ...
