Search for point sources of high energy neutrinos with final data from AMANDA-II (2009)

Abbasi, R, Ackermann, M, Adams, J, Descamps, Freija, Ryckbosch, Dirk, ...

We present a search for point sources of high energy neutrinos using 3.8 yr of data recorded by AMANDA-II during 2000-2006. After reconstructing muon tracks and applying selection criteria designed...

The IceCube data acquisition system: Signal capture, digitization, and timestamping (2009)

Abbasi, R, Ackermann, M, Adams, J, Descamps, Freija, Feusels, Tom, ...

IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules...

Helicity dependence of the total inclusive cross section on the deuteron (2009)

Ahrens, J, Altieri, S, Annand, JRM, Ryckbosch, Dirk

A measurement of the helicity dependence of the total inclusive photoabsorption cross section on the deuteron was carried out at MAMI (Mainz) in the energy range 200 < E gamma < 800 MeV. The...

A new measurement of the structure functions P-LL-P-TT/epsilon and P-LT in virtual Compton scattering at Q(2)=0.33 (GeV/c)(2) (2008)

Janssens, Peter, Doria, L, Achenbach, P, Ryckbosch, Dirk, Van Hoorebeke, Luc, ...

The cross-section of the ep -> e'p'gamma reaction has been measured at Q(2) = 0.33 (GeV/c)(2). The experiment was performed using the electron beam of the MAMI accelerator and the standard detector...

Measurement of parton distributions of strange quarks in the nucleon from charged-kaon production in deep-inelastic scattering on the deuteron (2008)

Airapetian, A, Akopov, N, Akopov, Z, Bruell, A, Elschenbroich, U, Hommez, B, ...

The momentum and helicity density distributions of the strange quark sea in the nucleon are obtained in leading order from charged-kaon production in deep-inelastic scattering on the deuteron. The...

Evidence for a transverse single-spin asymmetry in leptoproduction of pi(+)pi(-) pairs (2008)

Airapetian, A, Akopov, N, Akopov, Z, Elschenbroich, U, Hommez, B, Maiheu, B, ...

A single-spin asymmetry was measured in the azimuthal distribution of pi(+)pi(-) pairs produced in semi-inclusive deep-inelastic scattering on a transversely polarized hydrogen target. For the first...

Measurement of azimuthal asymmetries with respect to both beam charge and transverse target polarization in exclusive electroproduction of real photons (2008)

Airapetian, A, Akopov, N, Akopov, Z, Elschenbroich, U, Joosten, S, Maiheu, B, ...

Azimuthal asymmetries in exclusive electroproduction of real photons are measured for the first time with respect to transverse target polarisation, providing new constraints on Generalized Parton...

SOLAR ENERGETIC PARTICLE SPECTRUM ON 2006 DECEMBER 13 DETERMINED BY IceTop (2008)

Abbasi, R, Ackermann, M, Adams, J, Descamps, Freija, Ryckbosch, Dirk, Van Overloop, Arne

On 2006 December 13 the IceTop air shower array at the South Pole detected a major solar particle event. By numerically simulating the response of the IceTop tanks, which are thick Cerenkov detectors...

The GDH-Detector (2002)

Helbing, K, Anton, G, Fausten, M, Menze, D, Michel, T, Nagel, A, ...

For the GDH-Experiment at ELSA, the helicity dependent total photoabsorption cross-section is to be determined. These measurements will be performed with the newly developed GDH-Detector which is...

Single-spin azimuthal asymmetry in exclusive electroproduction of pi(+) mesons (2002)

Airapetian, A, Akopov, N, Akopov, Z, Hommez, B, Ryckbosch, Dirk, Tytgat, Michael, ...

A single-spin asymmetry in the distribution of exclusively produced pi(+) mesons azimuthally around the virtual photon direction relative to the lepton scattering plane has been measured for the...
