“…8 as a function of the monopole velocity b. The limits reported by MACRO [12] for an isotropic flux of monopoles, Baikal [13] and AMANDA [14] for upgoing monopoles are also given, as well as the theoretical Parker bound [11]. The flux limit obtained by this analysis improves by a factor of three the upper limits on the upgoing monopole flux for velocities above the Cherenkov threshold and extends these limits to lower velocities than limits obtained by previous neutrino telescope analyses.…”

“…For relativistic magnetic monopoles (b J 0.8), stronger bounds were reported by the Baikal and AMANDA neutrino telescopes. The Baikal neutrino telescope NT200 has set an upper limit of 4.6 Â 10 À17 cm À2 s À1 sr À1 on the flux of monopoles for b ' 1 [13], while the AMANDA-II limit at b ' 1 is 3.8 Â 10 À17 cm À2 s À1 sr À1 [14]. More recently, experiments based on radio detection reported stronger upper limits for ultrarelativistic magnetic monopoles.…”

a b s t r a c tMagnetic monopoles are predicted in various unified gauge models and could be produced at intermediate mass scales. Their detection in a neutrino telescope is facilitated by the large amount of light emitted compared to that from muons. This paper reports on a search for upgoing relativistic magnetic monopoles with the ANTARES neutrino telescope using a data set of 116 days of live time taken from December 2007 to December 2008. The one observed event is consistent with the expected atmospheric neutrino and muon background, leading to a 90% C.L. upper limit on the monopole flux between 1.3 Â 10 À17 and 8.9 Â 10 À17 cm À2 s À1 sr À1 for monopoles with velocity b P 0.625.

This Letter presents a search for magnetic monopoles with the ATLAS detector at the CERN Large Hadron Collider using an integrated luminosity of 2:0 fb À1 of pp collisions recorded at a center-of-mass energy of ffiffi ffi s p ¼ 7 TeV. No event is found in the signal region, leading to an upper limit on the production cross section at 95% confidence level of 1:6= fb for Dirac magnetic monopoles with the minimum unit magnetic charge and with mass between 200 GeV and 1500 GeV, where is the monopole reconstruction efficiency. The efficiency is high and uniform in the fiducial region given by pseudorapidity j j < 1:37 and transverse kinetic energy 600-700 < E kin sin < 1400 GeV. The minimum value of 700 GeV is for monopoles of mass 200 GeV, whereas the minimum value of 600 GeV is applicable for higher mass monopoles. Therefore, the upper limit on the production cross section at 95% confidence level is 2 fb in this fiducial region. Assuming the kinematic distributions from Drell-Yan pair production of spin-1=2 Dirac magnetic monopoles, the efficiency is in the range 1%-10%, leading to an upper limit on the cross section at 95% confidence level that varies from 145 fb to 16 fb for monopoles with mass between 200 GeV and 1200 GeV. This limit is weaker than the fiducial limit because most of these monopoles lie outside the fiducial region.

a b s t r a c tThe construction of a km 3 -scale neutrino telescope -the Gigaton Volume Detector (GVD) in Lake Baikal -is the central goal of the Baikal collaboration. During the R&D phase of the GVD project in 2008-2010 years the basic elements of GVD -new optical modules, FADC readout units, underwater communications and trigger systems -have been developed, produced and tested in situ by long-term operating prototype strings in Lake Baikal. The prototyping phase of the GVD project has been started in April 2011 with the installation of a three string array (prototype cluster) which comprises all basic elements and systems of the GVD-telescope in Lake Baikal. We describe configuration and technical design of the GVD, present selected results obtained during 2008-2010 with prototype strings, and describe configuration and design of the 2011 prototype cluster.
