['The Linear Collider Forum is an initiative born within the Helmholtz-Alliance \xe2\x80\x9dPhysics at the Terascale\xe2\x80\x9d, a network of German Universities and Research Centers working in high-energy particle physics. Yearly dedicated meetings focus on the physics case and the technologies at a future linear collider, covering both the ILC and CLIC concepts. In February 2012 an extended meeting with significant international participation was dedicated to the discussion of physics scenarios to strengthen and update the case...

Technical Design Report: European XFEL DAQ and DM Computing – 2009 Public Version

S. Esenov, K. Wrona & Youngman
This document describes the proposed computing model for the initial phase of operation of the European XFEL (EuXFEL) facility. In recognition of the overlap and interdependence of online data acquisition (DAQ) and offline data management (DM), both online and offline handling will be reviewed. The DAQ scope covers the control and readout systems in the photon beam lines, experimental hutches, laser and computing rooms in the experimental hall, and interaction with the electron machine control...

Hard Exclusive $\phi$ meson leptoproduction at HERMES.

Mayya Golembiovskaya, Armine Rostomyan, Sergey Yaschenko & Denis Veretennikov
AThe HERMES experiment at DESY, Hamburg collected a set of data on hard exclusive vector meson ($\rho^{0}$, $\phi$ , $\omega$) leptoproduction using the 27.6 GeV self-polarized lepton beam of HERA accelerator and a longitudinally or transversely polarized or unpolarized gas target. The latest results for spin density matrix elements of exclusive $\phi$ meson production using the full statistics collected at HERMES are presented. Conclusions on the helicity amplitudes, which are related to spin density matrix...

Fragmentation Functions at Belle.

Martin Leitgab
Fragmentation functions (FFs) describe the formation of final state particles from a partonic initial state. Precise knowledge of these functions is a key ingredient in accessing quantities such as the nucleon spin structure in semi-inclusive deep-inelastic scattering and proton proton collisions. However, fragmentation functions can currently not be determined from first principles Quantum Chromodynamics and have to be extracted from experimental data. The Belle experiment at KEK, Japan, provides a large data sample for high...

Constraining quark angular momentum with the Sivers function.

Alessandro Bacchetta & Marco Radici
Currently, the best way to determine quark total angular momentum requires the knowledge of the generalized parton distribution $E$ in the forward limit. We present the results of a recent work where we assumed a connection between this function and the Sivers transverse-momentum distribution. Using this assumption, we fitted at the same time nucleon anomalous magnetic moments and semi-inclusive single-spin asymmetries. This allowed us to give an estimate of the total angular momentum carried by...

Tau (or no) leptons in top quark decays at hadron colliders.

Michele Gallinaro
Measurements in the final states with taus or with no-leptons are among the most challenging as they are those with the smallest signal-to-background ratio. However, these final states are of particular interest as they can be important probes of new physics. Tau identification techniques and cross section measurements in top quark decays in these final states are discussed. The results, limited by systematical uncertainties, are consistent with standard model predictions, and are used to set...

Inclusive single top cross section at the LHC.

Rebeca Gonzalez Suarez
The three single-top-quark production modes are presented. The t-channel, established at the Tevatron, has the highest production rate and its cross-section has been measured at the LHC at 7 and 8~TeV. Evidence of the tW associated production was presented with 7~TeV data by ATLAS and CMS and observation was achieved at 8~TeV by the CMS experiment. An upper limit on the s-channel cross-section was set with 7~TeV data by ATLAS.

Measurements of $\mathbf{t\bar t} \pmb{\gamma}$ , $\mathbf{t\bar t + Z}$, and $\mathbf{t\bar t + W}$ production.

James Keaveney
Measurements of the production of top quark pairs in association with electroweak vector bosons from the CMS, ATLAS and CDF collaborations are presented. The CDF collaboration measures the cross section of top pair plus photon production and the ratio of this cross section the to inclusive top pair cross section using 6 fb$^{-1}$ of data at $\sqrt{s} = 1.96$ TeV with the results $\sigma_{t\bar{t}\gamma} = 0.18 \pm 0.07 (stat.) \pm 0.04 (sys.) \pm 0.01 (lumi.)$...

Conceptual Design Report: Scientific Instrument Spectroscopy and Coherent Scattering (SCS)

A. Scherz, O. Krupin, J. Buck, N. Gerasimova, G. Palmer, N. Poolton & L. Samoylova
This document reports on the present status of the conceptual design of the Spectroscopy and Coherent Scattering (SCS) scientific instrument at European XFEL. The SCS instrument is one of the six baseline instruments of the facility. It will cover a large range of scientific areas in the soft X-ray energy range of 0.25–3 keV, provide instrumentation that opens new scientific directions taking advantage of the unique European XFEL properties, and serve a broad scientific user...
