Observation of top quark production in proton-nucleus collisions
Georgios Konstantinos Krintiras
The multi-TeV energies available at LHC have opened up the possibility to measure, for the first time, various large-mass elementary particles in nuclear collisions. The current st…
Indirect dark matter searches in the dwarf satellite galaxy Ursa Major II with the MAGIC Telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +142
The dwarf spheroidal galaxy Ursa Major II (UMaII) is believed to be one of the most dark-matter dominated systems among the Milky Way satellites and represents a suitable target fo…
MAGIC Contributions to the 35th International Cosmic Ray Conference (ICRC2017)
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +143
MAGIC (Major Atmospheric Gamma Imaging Cherenkov) is a system of two 17 m diameter, F/1.03 Imaging Atmospheric Cherenkov Telescopes (IACT). They are dedicated to the observation of…
Observation of top quark production in proton-nucleus collisions
CMS Collaboration
The first observation of top quark production in proton-nucleus collisions is reported using proton-lead data collected by the CMS experiment at the CERN LHC at a nucleon-nucleon c…
Constraining Lorentz invariance violation using the Crab Pulsar emission observed up to TeV energies by MAGIC
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +142
Spontaneous breaking of Lorentz symmetry at energies on the order of the Planck energy or lower is predicted by many quantum gravity theories, implying non-trivial dispersion relat…
Performance of the MAGIC telescopes under moonlight
D. Guberman, P. Colin
MAGIC, a system of two imaging atmospheric Cherenkov telescopes, achieves its best performance under dark conditions, i.e. in absence of moonlight or twilight. Since operating the…
Search for very-high-energy gamma-ray emission from the microquasar Cygnus X-1 with the MAGIC telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +144
The microquasar Cygnus X-1 displays the two typical soft and hard X-ray states of a black-hole transient. During the latter, Cygnus X-1 shows a one-sided relativistic radio-jet. Re…
Search for evidence of the type-III seesaw mechanism in multilepton final states in proton-proton collisions at sqrt(s) = 13 TeV
CMS Collaboration
A search for a signal consistent with the type-III seesaw mechanism in events with three or more electrons or muons is presented. The data sample consists of proton-proton collisio…
MAGIC observations of the microquasar V404 Cygni during the 2015 outburst
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +142
The microquasar V404 Cygni underwent a series of outbursts in 2015, June 15-31, during which its flux in hard X-rays (20-40 keV) reached about 40 times the Crab Nebula flux. Becaus…
Measurement of the differential cross sections for the associated production of a W boson and jets in proton-proton collisions at sqrt(s) = 13 TeV
CMS Collaboration
A measurement of the differential cross sections for a W boson produced in association with jets in the muon decay channel is presented. The measurement is based on 13 TeV proton-p…
Search for direct production of supersymmetric partners of the top quark in the all-jets final state in proton-proton collisions at sqrt(s) = 13 TeV
CMS Collaboration
A search for direct production of top squark pairs in events with jets and large transverse momentum imbalance is presented. The data are based on proton-proton collisions at a cen…
Observation of the Black Widow B1957+20 millisecond pulsar binary system with the MAGIC telescopes
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +145
B1957+20 is a millisecond pulsar located in a black widow type compact binary system with a low mass stellar companion. The interaction of the pulsar wind with the companion star w…
Measurement of the semileptonic tt-bar gamma production cross section in pp collisions at sqrt(s) = 8 TeV
CMS Collaboration
A measurement of the cross section for top quark-antiquark (tt-bar) pairs produced in association with a photon in proton-proton collisions at sqrt(s) = 8 TeV is presented. The ana…

First Multi-wavelength Campaign on the Gamma-ray-loud Active Galaxy IC 310
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +160
The extragalactic VHE gamma-ray sky is rich in blazars. These are jetted active galactic nuclei viewed at a small angle to the line-of-sight. Only a handful of objects viewed at a…
MAGIC detection of very high energy gamma-ray emission from the low-luminosity blazar 1ES 1741+196
MAGIC Collaboration, M. L. Ahnen, S. Ansoldi +159
We present the first detection of the nearby (z=0.084) low-luminosity BL Lac object 1ES 1741+196 in the very high energy (VHE: E100 GeV) band. This object lies in a triplet of i…
