Analyses of gD*sDK and gB*sBK vertices in QCD sum rules
(IOP Publishing, 2012)The coupling constants g D*sDK and g B*sBK are calculated in the framework of QCD sum rules. We evaluate the correlation functions of these vertices considering both D(B) and K mesons off-shell and obtain the results as g ... -
Analysis of Ds*DK1 (Bs*BK1) coupling constants within QCD sum rules
(IOP Publishing, 2012)We compute the strong coupling constants for D*sDK1 and B*sBK1 vertices within the QCD sum rules. The coupling constants are calculated for both D(B) and K1 off-shell mesons. -
Analysis of the semileptonic transition of heavy Xi(Q) baryon to Xi baryon in Light Cone QCD Sum Rules
(Elsevier, 2013-12)This study presents the analysis of form factor calculations of semileptonic transitions of heavy baryons via light cone QCD sum rules. The work covers the semileptonic transitions of the Xi(b) and Xi(c) baryons. The form ... -
∑b,c to nucleon transitions in light cone QCD sum rules
(American Institute of Physics, 2011)The loop level flavor changing neutral current transitions of the ∑b→ nl+l-and ∑c→ pl+l- are investigated in the light cone QCD sum rules approach. Using the most general form of the interpolating current for ∑Q, Q =b or ... -
Baryon-baryon-meson coupling constants in QCD
(AIP Publishing, 2010)The strong coupling constant of decuplet and octet baryons to vector and pseudoscalar mesons are calculated in light cone QCD sum rules in general case and when the SU(3)f symmetry is taken into account. A comparison of ... -
CAST - A CERN experiment to search for solar axions
(American Institute of Physics, 2007)The CAST experiment at CERN is the only running solar axion telescope. The first results obtained so far with CAST - PHASE I is presented, which compete with the best astrophysically derived limits of the axion-to-photon ... -
CAST: Recent results & future outlook
(Verlag Deutsches Elektronen-Synchrotron, 2010-07)The CAST (CERN Axion Solar Telescope) experiment is searching for solar axions by their conversion into photons inside the magnet pipes of an LHC dipole. The analysis of data taken so far has shown no signal above the ... -
CAST: Status and latest results
(Hamburg Verlag, 2011)In July 2011 CAST finished the data-taking of its nominal programme having scanned axion masses up to ∼ 1.18 eV/c2. Here we present the first results of the data taken in 2008 first year of the last data-taking campaign ... -
Decay constants of heavy vector mesons at finite temperature
(IOP Publishing, 2012)This study deals with determination of the decay constants of heavy vector mesons in the framework of the thermal QCD sum rules. We calculate both thermal spectral density and non-perturbative contributions taking into ... -
Decay constants of the charmed tensor mesons at finite temperature
(American Institute of Physics, 2016-01)Investigation of the thermal properties of the mesons with higher spin is one of the important problems in the hadron physics. At finite temperature, the Lorentz invariance is broken by the choice of a preferred frame of ... -
Decay rate measurement of perylene dye molecules attached to porous silicon nanostructures
(SPIE, 2008)The radiative decay rates of perylene dye molecules, attached to silicon nano-rods are investigated by means of timeresolved fluorescence experiments. The decay rates of dye molecules in the vicinity of silicon nano-rods ... -
Effect of tissue heterogeneity on detectability of optical signals
(SPIE, 2006)Vascularization (hemoglobin concentration) is the main intrinsic contrast in near infrared optics and may be considered as the background heterogeneity or biological noise. This noise causes complexity of the assessment ... -
Final structure & design parameters of TARLA RF system
(JACoW, 2014-07-01)Turkish Accelerator and Radiation Laboratory in Ankara (TARLA) is an oscillator mode IR-FEL facility which is under construction since 2011. ELBE licensed superconducting modules housing TESLA RF cavities have been ... -
Fourth SM family and higgs at hadron colliders
(CERN, 2008-09-04)Higgs Boson production at hadron colliders is dominated by gluon-gluon fusion process, hence any change in the cross-section of the gluon-gluon fusion will practically result with the same amount of change on the total ... -
Future axion searches with the International Axion Observatory (IAXO)
(IOP Publishing, 2013)The International Axion Observatory (IAXO) is a new generation axion helioscope aiming at a sensitivity to the axion-photon coupling of gaγ ∼ few × 10-12 GeV-1, i.e. 1-1.5 orders of magnitude beyond the one achieved by ... -
