Abstract In this note, we briefly review some theory aspects of Quantum Chromodynamics at the future circular lepton collider (FCC-ee).

h-point standard addition method (hpsam) with simultaneous addition of both analytes in nonaqueous solution was applied for determination of levonorgestrel (lev) and ethinyl estradiol (ee)  in ld and hd tablets. the results showed that, simultaneous determination could be performed with the ratio 1 to 5 of lev-ee. the lod for lev and ee were obtained 5.1×10 -7 and 9.6×10 -7 m, respectively, and...

Abstract Muons provide a clean experimental signature, typically traversing the whole apparatus without decaying. Muon detection systems are therefore usually located at rather large distance from primary interaction vertex after all other sub-detectors. As such, apparatuses FCC-ee will certainly employ very muon systems, covering areas of few thousand square meters. For obvious reasons cost, m...

In the standard effective V - A theory of low-energy weak interactions (i.e. in Standard Model (SM)) we analyze structure correlation coefficients S(E_e) and U(E_e), where E_e is electron energy. These were introduced to electron-energy angular distribution neutron beta decay by Ebel Feldman ( Nucl. Phys. 4, 213 (1957)) addition set proposed Jackson et al. (Phys. Rev. 106, 517 (1957)). The $S(E...

this article emphasizes the findings of a survey conducted to find out the views of students on the environmental education (ee) in iranian secondary school (ss) curriculum. a total of six hundred students from forty secondary schools, randomly selected ss from five zones in tehran city responded to the questionnaire. two research questions were asked while two hypotheses were tested in this st...
