A Method for the Precision Mass Measurement of the Stop Quark at the International Linear Collider

Ayres Freitas, Caroline Milstene, Michael Schmitt +1

Many supersymmetric models predict new particles within the reach of the next generation of colliders. For an understanding of the model structure and the mechanism(s) of symmetry…

Black hole formation and slow-roll inflation

Kazunori Kohri, David H. Lyth, Alessandro Melchiorri

Black hole formation may occur if the spectrum of the curvature perturbation ζincreases strongly as the scale decreases. As no such increase is observed on cosmological scales, bla…

Type-II Seesaw at Collider, Lepton Asymmetry and Singlet Scalar Dark Matter

John McDonald, Narendra Sahu, Utpal Sarkar

We propose an extension of the standard model with a B-L global symmetry that is broken softly at the TeV scale. The neutrinos acquire masses through a type-II seesaw while the lep…

Supergravity and Two-Field Inflation Effects in Right-Handed Sneutrino-Modified D-term Inflation

Chia-Min Lin, John McDonald

We extend previous work on the minimal D-term inflation model modified by Right-Handed (RH) sneutrino fields to include additional inflaton-sector SUGRA corrections and two-field i…

Cosmological Constraints on Unparticles as Continuous Mass Scalars

John McDonald

We study the cosmological constraints on unparticle interactions and the temperature of the Universe for the case where unparticle states can be modelled as continuous mass particl…

Unifying inflation and dark matter with neutrino masses

Rouzbeh Allahverdi, Bhaskar Dutta, Anupam Mazumdar

We propose a simple model where a {\it gauge invariant inflaton} is responsible for cosmic inflation and generates the seed for structure formation, while its relic {\it thermal} a…
