A Study of the Early Cosmic Dynamics in a Multifield Model of Inflation and Curvature Perturbations

Advances in Astronomy, Volume 2024, Issue 1, 2024.
In this work, we study the cosmological dynamics of the early universe by employing a small field potential in the context of multifield inflation. By investigating analytically the cosmological observables, such as the number of e‐folds N, potential slow‐roll parameters ϵV, ηV, and spectral index ns which carry significant information, we show that ...

Superstring cosmology for N_4 = 1 -> 0 superstring vacua

, 2010
We study the cosmology of perturbative heterotic superstring theory during the radiation-like era for semi-realistic backgrounds with initial $\N=1$ supersymmetry.

Supersymmetry breaking due to moduli stabilization in string theory [PDF]

, 2011
We consider the phenomenological consequences of fixing compactification moduli. In the simplest KKLT constructions, stabilization of internal dimensions is rather soft: weak scale masses for moduli are generated, and are of order m_\sigma ~ m_{3/2}.

Higgs Information and NMSSM at the Large Hadron Collider

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
Information theory has proven to be a worthwhile tool for investigating the implications of the Higgs sector in the Next‐to‐Minimal Supersymmetric Standard Model (NMSSM) using Higgs information at the Large Hadron Collider (LHC) assessed through the entropy constructed by means of the branching ratios of decay channels of the Higgs boson.

Duality after Supersymmetry Breaking [PDF]

, 1998
Starting with two supersymmetric dual theories, we imagine adding a chiral perturbation that breaks supersymmetry dynamically. At low energy we then get two theories with soft supersymmetry-breaking terms that are generated dynamically.

Axion Models with High-Scale Supersymmetry Breaking

, 2004
Inspired by the possibility of high-scale supersymmetry breaking in the string landscape where the cosmological constant problem and the gauge hierarchy problem can be solved while the strong CP problem is still a challenge for naturalness, we propose a ...

Softness of Supersymmetry Breaking on the Orbifold $T^2/Z_2$ [PDF]

, 2005
We consider supersymmetry breaking due to a Scherk-Schwarz twist or localized mass terms in 6d ${\cal N}=1$ supersymmetric gauge theory compactified on the orbifold $T^2/Z_2$.

Superspace higher derivative terms in two dimensions

Journal of High Energy Physics, 2017
We study (2, 2) and (4, 4) supersymmetric theories with superspace higher derivatives in two dimensions. A characteristic feature of these models is that they have several different vacua, some of which break supersymmetry.
