A distance conjecture beyond moduli?

Journal of High Energy Physics
The distance conjecture states that for theories with moduli coupled to gravity a tower of states becomes exponentially light in the geodesic distance in moduli space. This specifies how effective field theories break down for large field values. However,

Intersecting end of the world branes

Journal of High Energy Physics
Dynamical cobordisms implement the swampland cobordism conjecture in the framework of effective field theory, realizing codimension-1 end of the world (ETW) branes as singularities at finite spacetime distance at which scalars diverge to infinite field ...

The dynamics of cosmological scenarios inspired by quantum gravity [PDF]

, 2006
PhDIn this thesis we study the dynamics of cosmological scenarios inspired by quantum gravity. Part I investigates novel features of the semi-classical regime of homogeneous and isotropic loop quantum cosmology.

Generalized three-family supersymmetric Pati-Salam models from Type IIA intersecting D6-branes

Journal of High Energy Physics
Generalizing three-family chiral fermion conditions to I ac = −(3 + h) and I a c ′ = h $$ {I}_{a{c}^{\prime }}=h $$ , with positive integer h, we extend the landscape of three-family N = 1 $$ \mathcal{N}=1 $$ supersymmetric Pati-Salam models in a broader

The N $$ \mathcal{N} $$ = 1 supersymmetric Pati-Salam models with extra SU 2 L 2 / R 2 $$ SU{(2)}_{L_2/{R}_2} $$ gauge symmetry from intersecting D6-branes

Journal of High Energy Physics
By introducing an extra stack of D6-branes to standard N $$ \mathcal{N} $$ = 1 supersymmetric Pati-Salam models, we extend the landscape of its complete search.

Using the Virasoro conditions to revise the model of a quark-gluon string fragmentation

Journal of High Energy Physics
Quark-gluon string fragmentation is usually seen as a universal process with its physics remaining unchanged for different colliding systems and center-of-mass energy.

The bubble of nothing under T-duality

Journal of High Energy Physics
The bubble of nothing is a solution to Einstein’s equations where a circle shrinks and pinches off smoothly. As such, it is one of the simplest examples of a dynamical cobordism to nothing.

String Phenomenology 2019

, 2019
An anti-D3-brane plays a crucial role in the construction of semi-realistic cosmological models in string theory. Part of its action provides an uplift term that has been used to lift AdS solutions to phenomenological viable dS vacua in the KKLT and LVS ...
