First Measurement of Charged Current Cross Sections at HERA with Longitudinally Polarised Positrons
H1 Collaboration
Data taken with positrons of different longitudinal polarisation states in collision with unpolarised protons at HERA are used to measure the total cross sections of the charged cu…
High brightness temperatures and circular polarisation in extra-galactic radio sources
J. G. Kirk, O. Tsang
Some rapidly variable extra-galactic radio sources show very high brightness temperatures T_B>10^{12}K and high degrees of circular polarisation (1%). Standard synchrotron models t…

We report a measurement of meson production in central Pb+Au collisions at E/A=158 GeV. For the first time in heavy-ion collisions, mesons were reconstructed in the…
Theory of Neutrinos: A White Paper
R. N. Mohapatra, S. Antusch, K. S. Babu +29
During 2004, four divisions of the American Physical Society commissioned a study of neutrino physics to take stock of where the field is at the moment and where it is going in the…
Nonlinear resonance absorption in laser-cluster interaction
M. Kundu, D. Bauer
Rare gas or metal clusters are known to absorb laser energy very efficiently. Upon cluster expansion the Mie plasma frequency may become equal to the laser frequency. This linear r…
Volume and Quark Mass Dependence of the Chiral Phase Transition
J. Braun, B. Klein, H. -J. Pirner +1
We investigate chiral symmetry restoration in finite spatial volume and at finite temperature by calculating the dependence of the chiral phase transition temperature on the size o…
New evidence for strong nonthermal effects in Tycho's supernova remnant
H. J. Voelk, E. G. Berezhko, L. T. Ksenofontov
For the case of Tycho's supernova remnant (SNR) we present the relation between the blast wave and contact discontinuity radii calculated within the nonlinear kinetic theory of cos…
A Smart Pixel Camera for future Cherenkov Telescopes
German Hermann, Svenja Carrigan, Bernhard Glück +1
The Smart Pixel Camera is a new camera for imaging atmospheric Cherenkov telescopes, suited for a next generation of large multi-telescope ground based gamma-ray observatories. The…
Early-Time Observations of the GRB 050319 Optical Transient
R. M. Quimby, E. S. Rykoff, S. A. Yost +18
We present the unfiltered ROTSE-III light curve of the optical transient associated with GRB 050319 beginning 4 s after the cessation of gamma-ray activity. We fit a power-law func…
Next generation of IACT arrays: scientific objectives versus energy domains
Felix Aharonian
Several key motivations and perspectives of ground based gamma-ray astronomy are discussed in the context of the specifics of detection techniques and scientific topics/objectives…
Strong-field approximation for harmonic generation in diatomic molecules
Ciprian C. Chirila, Manfred Lein
The generation of high-order harmonics in diatomic molecules is investigated within the framework of the strong-field approximation. We show that the conventional saddle-point appr…
Ionization suppression of excited atomic states beyond the stabilization regime
Andreas Staudt, Christoph H. Keitel, John S. Briggs
A two-dimensional model atom is employed to study the ionization behavior of initially excited atomic states in highly-frequent intense laser pulses beyond the dipole approximation…
Magnetic-dipole transition probabilities in B-like and Be-like ions
I. I. Tupitsyn, A. V. Volotka, D. A. Glazov +5
The magnetic-dipole transition probabilities between the fine-structure levels (1s^2 2s^2 2p) ^2P_1/2 - ^2P_3/2 for B-like ions and (1s^2 2s 2p) ^3P_1 - ^3P_2 for Be-like ions are…
Comparison of classical and second quantized description of the dynamic Stark shift
M. Haas, U. D. Jentschura, C. H. Keitel
We compare the derivation of the dynamic Stark shift of hydrogenic energy levels in a classical framework with an adiabatically damped laser-atom interaction, which is equivalent t…
