The ATLAS muon micromegas R&D project: towards large-size chambers for the s-LHC
Alexopoulos, T.; Altıntaş, Azmi Ali; Alviggi, M.; Arık, Metin; Çetin, Serkant Ali; Chernyatine, V. (IOP Publishing, 2009-12)Detectors based on the bulk-Micromegas technology exhibit position resolution better than 100 m m at counting rates of up to several tens of kHz/cm(2), along with trigger capabilities. These characteristics, combined with ... -
Can hyperbolic phase of Brans - Dicke field account for Dark Matter?
Arık, Metin; Çalık, Mehmet; Çifter, Fulya (World Scientific Publishing, 2009-04)We show that the introduction of a hyperbolic phase of the Brans-Dicke (BD) field results in a flat vacuum cosmological solution of the Hubble parameter H and a fractional rate of change of the BD scalar field F, which ... -
A cosmological exact solution of generalized Brans - Dicke theory with complex scalar field and its phenomenological implications
Arık, Metin; Çalık, Mehmet; Katırcı, Nihan (Springer, 2011-12)When the Brans-Dicke theory is formulated in terms of the Jordan scalar field phi, the amount of dark energy is related to the mass of this field. We investigate a solution which is relevant to the late universe. We show ... -
Development of large size micromegas detector for the upgrade of the ATLAS muon system
Alexopoulos, T.; Altıntaş, Azmi Ali; Alviggi, M.; Arık, Metin; Çetin, Serkant Ali; Chernyatine, V. (Elsevier, 2010-05-11)With the luminosity upgrade of the LHC machine (SLHC, Super-LHC), the Muon system of the ATLAS experiment at CERN will also need a detector upgrade in the highest rapidity region. MAMMA, Muon ATLAS Micromegas Activity, is ... -
Friedmann equation for brans-dicke cosmology
Arık, Metin; Çalık, Mehmet; Sheftel, Mikhail S. (World Scientific Publishing, 2008-02)In the context of the Brans-Dicke scalar tensor theory of gravitation, the cosmological Friedmann equation which relates the expansion rate H of the universe to the various fractions of energy density is analyzed rigorously. ... -
Status and perspectives of the CAST experiment
Lakic, Biljana; Arık, Metin; Aune, Stephan; Barth, Kurt L.; Belov, Alexander S.; Borghi, Silvia (IOP Publishing, 2012)The CERN Axion Solar Telescope (CAST) is currently the most sensitive axion helioscope designed to search for axions produced by the Primakoff process in the solar core. CAST is using a Large Hadron Collider (LHC) test ...
