Chain Inflation in the Landscape: "Bubble Bubble Toil and Trouble"

Katherine Freese, Douglas Spolyar

In the model of Chain Inflation, a sequential chain of coupled scalar fields drives inflation. We consider a multidimensional potential with a large number of bowls, or local minim…

Physics Interplay of the LHC and the ILC

LC Study Group, G. Weiglein, T. Barklow +120

Physics at the Large Hadron Collider (LHC) and the International e+e- Linear Collider (ILC) will be complementary in many respects, as has been demonstrated at previous generations…

Hybrid Inflation and the Moduli Problem

Micha Berkooz, Michael Dine, Tomer Volansky

We revisit some questions in supersymmetric hybrid inflation (SHI). We analyze the amount of fine tuning required in various models, the problem of decay at the end of inflation an…

Twisted Split Fermions

Yuval Grossman, Roni Harnik, Gilad Perez +2

The observed flavor structure of the standard model arises naturally in "split fermion" models which localize fermions at different places in an extra dimension. It has, until now,…

New Ways to Soft Leptogenesis

Yuval Grossman, Tamar Kashti, Yosef Nir +1

Soft supersymmetry breaking terms involving heavy singlet sneutrinos provide new sources of lepton number violation and of CP violation. In addition to the CP violation in mixing,…

Is There a Peccei-Quinn Phase Transition?

Alexey Anisimov, Michael Dine

The nature of axion cosmology is usually said to depend on whether the Peccei-Quinn (PQ) symmetry breaks before or after inflation. The PQ symmetry itself is believed to be an acci…

Localized Supersoft Supersymmetry Breaking

Z. Chacko, Patrick J. Fox, Hitoshi Murayama

We consider supersymmetry breaking models in which the MSSM is extended to include an additional chiral adjoint field for each gauge group with which the the MSSM gauginos acquire…

Visible Effects of the Hidden Sector

M. Dine, P. J. Fox, E. Gorbatov +3

The renormalization of operators responsible for soft supersymmetry breaking is usually calculated by starting at some high scale and including only visible sector interactions in…

The mass difference from a dispersion relation

Adam F. Falk, Yuval Grossman, Zoltan Ligeti +2

We study the Standard Model prediction for the mass difference between the two neutral D meson mass eigenstates, . We derive a dispersion relation based on heavy quark effectiv…

Using untagged B^0 -> D K_S to determine gamma

M. Gronau, Y. Grossman, N. Shuhmaher +2

It is shown that the weak phase gamma=arg(-V_{ud}V^*_{ub}V_{cb}V_{cd}^*) can be determined using only untagged decays B/Bbar--> D K_S. In order to reduce the uncertainty in gamma,…
