Charm in DeepInelastic Scattering
/ Ball, Richard D (U. Edinburgh, Higgs Ctr. Theor. Phys. ; CERN) ; Bonvini, Marco (Oxford U., Theor. Phys.) ; Rottoli, Luca (Oxford U., Theor. Phys.)
We show how to extend systematically the FONLL scheme for inclusion of heavy quark mass effects in DIS to account for the possible effects of an intrinsic charm component in the nucleon. We show that when there is no intrinsic charm, FONLL is equivalent to SACOT to any order in perturbation theory, while when an intrinsic charm component is included FONLL is identical to ACOT, again to all orders in perturbation theory.

Sigma Models with Negative Curvature
/ Alonso, Rodrigo (UC, San Diego) ; Jenkins, Elizabeth E (UC, San Diego ; CERN) ; Manohar, Aneesh V (UC, San Diego ; CERN)
We construct Higgs Effective Field Theory (HEFT) based on the scalar manifold H^n, which is a hyperbolic space of constant negative curvature. The Lagrangian has a noncompact O(n,1) global symmetry group, but it gives a unitary theory as long as only a compact subgroup of the global symmetry is gauged. [...]

Searching for new spin0 resonances at LHCb
/ Haisch, Ulrich (Oxford U., Theor. Phys. ; CERN) ; Kamenik, Jernej F (CERN ; Stefan Inst., Ljubljana ; Ljubljana U.)
We study the phenomenology of light spin0 particles and stress that they can be efficiently searched for at the LHCb experiment in the form of dimuon resonances. Given the large production cross sections in the forward rapidity region together with the efficient triggering and excellent mass resolution, it is argued that LHCb can provide unique sensitivity to such states.

Statistical anisotropy from inflationary magnetogenesis
/ Giovannini, Massimo (CERN ; INFN, Milan Bicocca)
Provided the quantum fluctuations are amplified in the presence of a classical gauge field configuration the resulting curvature perturbations exhibit a mild statistical anisotropy which should be sufficiently weak not to conflict with current observational data. The curvature power spectra induced by weakly anisotropic initial states are computed here for the first time when the electric and the magnetic gauge couplings evolve at different rates as it happens, for instance, in the relativistic theory of van der Waals interactions. [...]

The Virtual Diphoton Excess
/ Stolarski, Daniel (CERN ; Ottawa Carleton Inst. Phys.) ; VegaMorales, Roberto (Granada U., Theor. Phys. Astrophys.)
Interpreting the excesses around 750 GeV in the diphoton spectra to be the signal of a new heavy scalar decaying to photons, we point out the possibility of looking for correlated signals with virtual photons. In particular, we emphasize that the effective operator that generates the diphoton decay will also generate decays to two leptons and a photon, as well as to four leptons, independently of the new resonance couplings to $Z\gamma$ and $ZZ$.

PostInflationary Gravitino Production Revisited

We revisit gravitino production following inflation. As a first step, we review the standard calculation of gravitino production in the thermal plasma formed at the end of postinflationary reheating when the inflaton has completely decayed. [...]

Renormalization of Horava Gravity

We prove perturbative renormalizability of projectable Horava gravity. The key element of the argument is the choice of a gauge which ensures the correct anisotropic scaling of the propagators and their uniform falloff at large frequencies and momenta. [...]
