Mixed NNLO QCD × electroweak corrections to single-Z production in pole approximation: differential distributions and forward-backward asymmetry / Dittmaier, Stefan (Freiburg U.) ; Huss, Alexander (CERN) ; Schwarz, Jan (Freiburg U.)
Radiative corrections in pole approximation, which are based on the leading contribution in a systematic expansion of amplitudes about resonance poles, naturally decompose into factorizable corrections attributed to the production or decay of the resonance and non-factorizable corrections induced by soft photon (or gluon) exchange between those subprocesses. In this paper we complete an earlier calculation of mixed QCD$\times$electroweak corrections of $\mathcal{O}(\alpha_s\alpha)$ to the neutral-current Drell-Yan cross section in pole approximation by including the previously neglected corrections that are solely related to the Z-boson production process.

Mixed NNLO QCD×electroweak corrections of $\mathcal{O}(N_f \alpha_s \alpha)$ to single-W/Z production at the LHC / Dittmaier, Stefan (Freiburg U.) ; Schmidt, Timo (Wurzburg U.) ; Schwarz, Jan (Freiburg U.)
First results on the radiative corrections of order O(N_f\alpha_s\alpha) are presented for the off-shell production of W or Z bosons at the LHC, where N_f is the number of fermion flavours. These corrections comprise all diagrams at O(\alpha_s\alpha) with closed fermion loops, form a gauge-invariant part of the next-to-next-to-leading-order corrections of mixed QCD x electroweak type, and are the ones that concern the issue of mass renormalization of the W and Z resonances.

First detection of the Crab Nebula at TeV energies with a Cherenkov telescope in dual-mirror Schwarzschild-Couder configuration: the ASTRI-Horn telescope / Lombardi, S. (Rome Observ. ; ASDC, Frascati) ; Catalano, O. (IASF, Palermo) ; Scuderi, S. (IASF, Milan) ; Antonelli, L.A. (Rome Observ. ; ASDC, Frascati) ; Pareschi, G. (Brera Observ.) ; Antolini, E.

We report on the first detection of very high-energy (VHE) gamma-ray emission from the Crab Nebula by a Cherenkov telescope in dual-mirror Schwarzschild-Couder (SC) configuration. The result has been achieved by means of the 4 m size ASTRI-Horn telescope, operated on Mt. [...]

Large-scale alignments from WMAP and Planck / Copi, Craig J. (Case Western Reserve U., CERCA) ; Huterer, Dragan (Michigan U.) ; Schwarz, Dominik J. (Bielefeld U.) ; Starkman, Glenn D. (CERN ; Case Western Reserve U., CERCA)
We revisit the alignments of the largest structures observed in the cosmic microwave background (CMB) using the seven and nine-year WMAP and first-year Planck data releases. The observed alignments -- the quadrupole with the octopole and their joint alignment with the direction of our motion with respect to the CMB (the dipole direction) and the geometry of the Solar System (defined by the Ecliptic plane) -- are generally in good agreement with results from the previous WMAP data releases. [...]

Lack of large-angle TT correlations persists in WMAP and Planck / Copi, Craig J. (Case Western Reserve U. ; Case Western Reserve U., CERCA) ; Huterer, Dragan (Michigan U.) ; Schwarz, Dominik J. (Bielefeld U.) ; Starkman, Glenn D. (Case Western Reserve U. ; CERN ; Case Western Reserve U., CERCA)
The lack of large-angle correlations in the observed microwave background temperature fluctuations persists in the final-year maps from WMAP and the first cosmological data release from Planck. We find a statistically robust and significant result: p-values for the missing correlations lying below 0.24 per cent (i.e. [...]

Large-Angle CMB Suppression and Polarisation Predictions / Copi, C.J. (Case Western Reserve U. ; Case Western Reserve U., CERCA) ; Huterer, D. (Michigan U.) ; Schwarz, D.J. (Bielefeld U.) ; Starkman, G.D. (Case Western Reserve U. ; Case Western Reserve U., CERCA ; CERN)
The anomalous lack of large angle temperature correlations has been a surprising feature of the CMB since first observed by COBE-DMR and subsequently confirmed and strengthened by WMAP. This anomaly may point to the need for modifications of the standard model of cosmology or may show that our Universe is a rare statistical fluctuation within that model. [...]

Can extragalactic foregrounds explain the large-angle CMB anomalies? / Rakic, Aleksandar (Bielefeld U.) ; Rasanen, Syksy (CERN) ; Schwarz, Dominik J. (Bielefeld U.)
We address the effect of an extended local foreground on the low-l anomalies found in the CMB. Recent X-ray catalogues point us to the existence of very massive superstructures at the 100 h^(-1) Mpc scale that contribute significantly to the dipole velocity profile. [...]

Particle cosmology / Schwarz, Dominik J (speaker) (Bielefeld University, D)
The understanding of the Universe at the largest and smallest scales traditionally has been the subject of cosmology and particle physics, respectively. Studying the evolution of the Universe connects today's large scales with the tiny scales in the very early Universe and provides the link between the physics of particles and of the cosmos. [...]

Microwave sky and the local Rees-Sciama effect / Rakic, Aleksandar (Bielefeld U.) ; Rasanen, Syksy (CERN) ; Schwarz, Dominik J. (Bielefeld U.)
The microwave sky shows unexpected features at the largest angular scales, among them the alignments of the dipole, quadrupole and octopole. Motivated by recent X-ray cluster studies, we investigate the possibility that local structures at the 100 h^-1 Mpc scale could be responsible for such correlations. [...]

Precision electroweak measurements on the $Z$ resonance / ALEPH Collaboration
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. [...]
