Diffraction in DIS on nuclear targets
N. N. Nikolaev, W. Schaefer, B. G. Zakharov +1
We discuss the implications of a strong enhancement of diffraction for multiproduction in DIS off nuclear targets. The predicted effects are large and observable at HERA. We presen…
Technical Design Report for the PANDA Solenoid and Dipole Spectrometer Magnets
The PANDA Collaboration, W. Erni, I. Keshelashvili +407
This document is the Technical Design Report covering the two large spectrometer magnets of the PANDA detector set-up. It shows the conceptual design of the magnets and their antic…
Secondary Reggeons in Diffractive Deep Inelastic Scattering - the Microscopic QCD Evaluation
W. Schaefer
We present the microscopic QCD evaluation of the secondary reggeon contribution to diffractive DIS. It is shown that the interference between Pomeron and Reggeon enters in the maxi…
Deconvolution of JWST/MIRI Images: Applications to an AGN Model and GATOS Observations of NGC 5728
M. T. Leist, C. Packham, D. J. V. Rosario +32
The superb image quality, stability and sensitivity of the JWST permit deconvolution techniques to be pursued with a fidelity unavailable to ground-based observations. We present a…
Physics Performance Report for PANDA: Strong Interaction Studies with Antiprotons
PANDA Collaboration, W. Erni, I. Keshelashvili +411
To study fundamental questions of hadron and nuclear physics in interactions of antiprotons with nucleons and nuclei, the universal PANDA detector will be built. Gluonic excitation…
Evidence for the coexistence of low-dimensional magnetism and long-range order in Ca3CoRhO6
M. Loewenhaupt, W. Schaefer, A. Niazi +1
We report the results of neutron powder diffraction studies on the spin-chain compound Ca3CoRhO6 in the temperature range 3 to 293 K. Bragg peaks due to magnetic ordering start app…
Diffractive DIS: back to triple-Regge phenomenology?
N. N. Nikolaev, W. Schaefer, B. G. Zakharov
We discuss the factorization breaking effects caused by the contribution to large rapidity gap events from DIS on secondary reggeons. Based on the triple-Regge phenomenology of had…
The Tensor Structure Function of the Deuteron at Small x
W. Schaefer
The dependence of the diffractive nuclear shadowing and the nuclear pion excess effect on the deuteron spin alignment leads to a substantial tensor polarisation of sea partons in t…
The Impact of NLO-Corrections on the Determination of the $\bar{u},\bar{d} Content of Nucleons from Drell-Yan Production
W. Schaefer
The interpretation of Drell-Yan production in terms of the antiquark densities depends on NLO corrections. Besides the NLO corrections to the familiar annihilation $q\bar{q}\to γ^…
Technical Design Report for PANDA Electromagnetic Calorimeter (EMC)
PANDA Collaboration, W. Erni, I. Keshelashvili +407
This document presents the technical layout and the envisaged performance of the Electromagnetic Calorimeter (EMC) for the PANDA target spectrometer. The EMC has been designed to m…
Diffractive structure function at very small beta and unitarity corrections in the color dipole Regge approach
W. Schaefer
Starting from the phenomenologically successful color dipole representation of the diffractive structure function, we identify the dominant contribution to the diffractive cross se…
Atomic Clock Ensemble in Space
L. Cacciapuoti, A. Busso, R. Jansen +25
The Atomic Clock Ensemble in Space (ACES) mission is developing high performance clocks and links for space to test Einstein's theory of general relativity. From the International…
Nonvanishing tensor polarization of sea quarks in polarized deuterons
N. N. Nikolaev, W. Schaefer
We propose two new sources of a substantial tensor polarization of sea partons in the deuteron: the diffractive nuclear shadowing which depends on the alignment of nucleons in the…
