A search for the exclusive production of the hadron by virtual photons has been performed in the channel . The data cover…
Search for Gamma-ray Spectral Lines from Dark Matter Annihilation up to 100 TeV towards the Galactic Center with MAGIC
MAGIC Collaboration, H. Abe, S. Abe +210
Line-like features in TeV -rays constitute a ''smoking gun'' for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov…
Measurements of production in Be+Be collisions at beam momenta from 19 to 150GeV/ in the NA61/SHINE experiment at the CERN SPS
SHINE Collaboration, A. Acharya, H. Adhikary +139
The NA61/SHINE collaboration studies at the CERN Super Proton Synchrotron (SPS) the onset of deconfinement in hadronic matter by the measurement of particle production in collision…
Strong lensing analysis of Abell 2744 with MUSE and Hubble Frontier Fields images
G. Mahler, J. Richard, B. Clément +13
We present an analysis of MUSE observations obtained on the massive Frontier Fields cluster Abell 2744. This new dataset covers the entire multiply-imaged region around the cluster…
Sivers asymmetry extracted in SIDIS at the hard scale of the Drell-Yan process at COMPASS
C. Adolph, M. Aghasyan, R. Akhunzyanov +223
Proton transverse-spin azimuthal asymmetries are extracted from the COMPASS 2010 semi-inclusive hadron measurements in deep inelastic muon-nucleon scattering in those four regions…
A spectroscopically confirmed z=1.327 galaxy-scale deflector magnifying a z~8 Lyman-Break galaxy in the Brightest of Reionizing Galaxies survey
R. L. Barone-Nugent, A. Sonnenfeld, J. S. B. Wyithe +6
We present a detailed analysis of an individual case of gravitational lensing of a Lyman-Break galaxy (LBG) in a blank field, identified in Hubble Space Telescope imaging…
Correlations between emission timescale of fragments and isospin dynamics in Sn+Ni and Sn+Ni reactions at 35 AMeV
E. De Filippo, A. Pagano, P. Russotto +51
We present a new experimental method to correlate the isotopic composition of intermediate mass fragments (IMF) emitted at mid-rapidity in semi-peripheral collisions with the emiss…
