Cosmic Rays Through the Higgs Portal
Speaker(s): Robert Mann
Abstract: An electroweak singlet coupling through the Higgs portal has a natural mass scale $m_Ssim m_h$. In this mass range its annihilation cross section is dominated by proximity to the $W$, $Z$ and Higgs peaks. Analysis of the $gamma$ ray signal from electroweak singlet annihilation in the mass range $80,... read more

LARGE Volume Scenarios and String Loops
Speaker(s): Michele Cicoli
Abstract: We study the necessary and sufficient topological conditions for general Calabi-Yaus to get a non-supersymmetric AdS exponentially large volume minimum of the scalar potential in flux compactifications of IIB string theory. It turns out that string loop corrections play a crucial role to realise exp... read more

Cosmology from CFHTLS-Wide Weak Lensing on Large Scales
Speaker(s): Michael Hudson
Abstract: I will discuss recent results from the Cosmic Shear component of the CFHT Legacy Survey. These results reach very large scales, allowing a measurement of poper spectrum of matter fluctuations in the linear regime, and of cosmological parameters.

Moduli stabilization and flavor structure in 5D SUGRA with multi moduli
Speaker(s): Yutaka Sakamura
Abstract: Moduli stabilization, SUSY breaking and flavor structure are discussed in 5D gauged supergravity models with two vector-multiplet moduli fields. One modulus field makes the fermion mass hierarchy while the other is relevant to the SUSY breaking mediation. We analyse the potential for the moduli from... read more

Large Scale Structure as a Probe of Gravitational Slip
Speaker(s): Scott Daniel
Abstract: Many modified gravity schemes predict a non-zero difference (``gravitational slip'') between the Newtonian and longitudinal perturbed metric potentials. Such a slip would affect the growth of large scale structure without altering the expansion history of the universe. We quantify the slip with a ne... read more

The anthropic solution to the strong CP problem and its cosmological implications.
Speaker(s): Fuminobu Takahashi
Abstract: We point out that the strong CP problem can be resolved by the anthropic principle. The key ideas are to allow explicit breaking(s) of the Peccei-Quinn symmetry which connects the problem to the cosmological constant problem, and to conjecture that the probability distribution of the vacuum energy i... read more

Bubbling AdS and Matrix Models
Speaker(s): Sera Cremonini
Abstract: 'In this talk we will focus on the supergravity duals of BPS states in N=4 Super Yang-Mills. In particular, we will describe how one can obtain a universal AdS bubbling picture for 1/4 and 1/8 BPS geometries, in analogy with the well-established 1/2 BPS droplet picture of LLM. In addition, we will s... read more
