Form factors in radiative pion decay

We perform an analysis of the form factors that rule the structure-dependent amplitude in the radiative pion decay. The resonance contributions to π → e νeγ decays are computed through the proper construction of the vector and axial-vector form factors by setting the QCD driven asymptotic properties of the three-point Green functions 〈V V P 〉 and 〈V AP 〉, and by demanding the smoothing of the f...

Decay factors and patterns of stones in open-air historical sites built of carbonate sedimentary stones

The number of historical open-air sites built of stone are relatively limited in comparison to the other historical artificial in Iran, but these sites include great significance in terms of value, historic and their knowledge of past. Since these stone poen-air sites are generally about two thousand years old, they have been exposed to decay factors for a long time. Many information and data o...

Dental decay and associated factors in Iranian three years old children

Objectives: The aim of this study was to assess dental caries and associated factors in children aged three years living in Varamin, Iran. Methods: Eight hundred and fifteen three-year-old children were recalled randomly through the records existing in healthcare centers of Varamin, Iran. Two hundred and three mothers were also examined to assess the relationship between the oral health of mot...
