F-theory family unification [PDF]
Journal of High Energy Physics, 2014 We propose a new geometric mechanism for naturally realizing unparallel three families of flavors in string theory, using the framework of F-theory. We consider a set of coalesced local 7-branes of a particular Kodaira singularity type and allow some of the branes to bend and separate from the rest, so that they meet only at an intersection point. Such

F-theory with quantized fluxes [PDF]
Advances in Theoretical and Mathematical Physics, 1999 We present evidence that the CHL string in eight dimensions is dual to F-theory compactified on an elliptic K3 with a $ _{0}(2)$ monodromy group. The monodromy group $ _{0}(2)$ allows one to turn on the flux of an antisymmetric two form along the base.

A note on orientifolds and F-theory [PDF]
Physics Letters B, 1997 An orientifold of Type-IIB theory on a $K3$ realized as a $Z_2$ orbifold is constructed which corresponds to F-theory compactification on a Calabi-Yau orbifold with Hodge numbers $(51, 3)$. The T-dual of this model is analogous to an orbifold with discrete torsion in that the action of orientation reversal has an additional phase on the twisted sectors,

Probing F-theory With Multiple Branes [PDF]
, 1996 We study multiple 3-branes on an F theory orientifold. The world-volume theory of the 3-branes is d=4, N=2 Sp(2k) gauge theory with an antisymmetric tensor and four flavors of matter in the fundamental.

Scanning the skeleton of the 4D F-theory landscape [PDF]
, 2017 A bstractUsing a one-way Monte Carlo algorithm from several different starting points, we get an approximation to the distribution of toric threefold bases that can be used in four-dimensional F-theory compactification.

PARALLELED CHARACTERS IN THE DRAMATIC WORKS OF HORTENSIA PAPADAT-BENGESCU [PDF]
Diversitate si Identitate Culturala in Europa, 2015 This article proposes a psychoanalytical approach to two paralleled literary characters whom Hortensia Papadat-Bengescu places into opposition in order to introduce her readers to feminine hypostases of wish fulfilment.

F Theory on K3xK3 and Instantons on 7-branes [PDF]
Nucl.Phys. B510 (1998) 232-246, 1997 We discuss N=2 supersymmetric compactifications to four dimensions from the point of view of F-theory and heterotic theory. In a relatively simple setup, we illustrate the spectral theory for vector bundles on K3xT^2 and discuss the heterotic -- F-theory map. The moduli space of instantons on the 7-brane wrapped around K3 is discussed from the point of

Exotic matter on singular divisors in F-theory [PDF]
, 2017 A bstractWe analyze exotic matter representations that arise on singular seven-brane configurations in F-theory. We develop a general framework for analyzing such representations, and work out explicit descriptions for models with matter in the 2-index ...

F-theory and linear sigma models [PDF]
, 1997 We present an explicit method for translating between the linear sigma model and the spectral cover description of SU(r) stable bundles over an elliptically fibered Calabi-Yau manifold.

Enhanced rates for diphoton resonances in the MSSM
Physics Letters B, 2017 We propose a simple mechanism for copiously producing heavy Higgs bosons with enhanced decay rates to two photons at the LHC, within the context of the Minimal Supersymmetric extension of the Standard Model (MSSM).
