Searching for cosmological magnetic fields in the diffuse gamma-ray background

Abstract: Several CP violating processes occurring in the early universe could have produced weak-field helical magnetic seed fields that would have subsequently grown, amplified via different types of dynamo mechanism, accounting for the presently observed astronomical-sized fields. The structure of these large-scale magnetic fields is imprinted on the gamma-ray sky through secondary cascades. Using data from the Fermi satellite we evaluate a CP odd statistic and find it to be non-zero above the $2 \sigma$ level. This results indicate a left-handed helical magnetic field of $10^{-14}G$ on $~10$ Mpc scales.

What Next on Axion-like Particles: Current Bounds and Discovery Opportunities

Abstract: Very light axion-like particles (ALPs) with a two-photon vertex are predicted in many extensions of the Standard Model of particle physics. Depending on the actual value of their mass, ALPs can play an important role in cosmology, being valuable dark matter candidates. The coupling with photons allows for ALP-photon mixing in external electromagnetic fields. This effect is exploited for direct searches of ALPs in laboratory experiments. The two-photon vertex would also induce the mixing with ALPs for photons emitted by distant astrophysical sources, and propagating in the large-scale cosmic magnetic fields. This mixing could produce signatures in astrophysical observations, ranging from the cosmic microwave background to the high-energy gamma-rays. In this talk I will present an overview of current bounds on ALPs and discovery opportunities in the planned laboratory and astrophysical experiments.

Real-time phenomena in finite-temperature QCD

Abstract: I present two topics in finite-temperature QCD: one concerns the pion quasiparticle and its dispersion relation in the low-temperature phase; the second concerns non-static screening masses in the high-temperature phase, the corresponding perturbative predictions and the relation of these masses to transport properties and the dilepton rate.

Ward identities and transport in 2+1 dimensions

Abstract: The Hall viscosity of chiral superfluids is determined by the angular momentum density. One can understand and generalize this relation using Ward identities of the energy-momentum tensor. Furthermore, the same identities connect viscosities and conductivities. A preliminary analysis in AdS/CFT reveals that the identities seem to be non-trivial in the sense that they cannot be derived simply from the asymptotic expansion of the solutions.

Looking for hidden supersymmetry

Abstract: After a brief review of the state of supersymmetry after RUN I of the LHC, it will be argued that the supersymmetric electroweak sector may play the leading role in its discovery. Experimental signatures of electroweakinos and the prospects for their discovery will be discussed.

Massive study of magnetized unquenched ABJM

Abstract: We study the physics of a magnetized probe D6-brane in the ABJM theory with unquenched massive flavor. We analyze the effect of the mass of the background branes in the magnetic catalysis of chiral symmetry breaking, and also the effect of the magnetic field on the meson spectrum. Besides, we obtain a non-commutative version of the background via a TsT rotation, which has an NSNS B2 field turned on, as an intermediate step towards a fully backreacted solution. In addition, we include new analytical solutions, perturbative in flavor, for the background functions.

Nonlinear effects and coarse-graining in general relativity

Abstract: I will discuss the nonlinear effects of general relativity which appear if we perform the coarse-graining of the fine structure of a solution. In particular I will discuss the effects of nested inhomogeneities extending over many scales.
