▪ Abstract We provide a pedagogical introduction to a recently studied class of
phenomenologically interesting string models known as Intersecting D-Brane Models. The …

Extra dimensions have interesting consequences for flavor physics. We consider a setup
where the standard model fermions and gauge fields reside in the bulk of a warped extra …

It is known that hidden U (1) gauge factors can couple to visible U (1) s through kinetic
mixing. This phenomenon is shown to occur in non-supersymmetric string set-ups, between …

The state of the art in D‐brane model building is briefly reviewed, focusing on recent
achievements in the construction of D= 4 𝒩= 1 type II string vacua with semi‐realistic gauge …

In this paper we describe the general geometrical framework of brane world constructions in
orientifolds of type IIA string theory with D6-branes wrap** 3-cycles in a Calabi–Yau 3 …

The effective field theory of the minimal low scale orientifold models is developed. It
describes universal features of related orientifold vacua in string theory. It contains, beyond …

We discuss tree level three and four point scattering amplitudes in type II string models with
matter fields localized at the intersections of D-brane wrap** cycles. Using conformal field …

String and field theory ideas have greatly influenced each other since the so-called second
string revolution. We review this interrelation paying particular attention to its …

The mass scale of fundamental strings can be as low as few TeV/c2 provided that spacetime
extends into large extra dimensions. We discuss the phenomenological aspects of weakly …

Motivated by recent experimental results on charm physics, we investigate implications of
the updated constraints of new physics in rare charm meson decays. We first reconsider …
