Scale dimension of chiral-symmetry breaking

Реэмер масщтаба нарущения киральной симметрии

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We estimate the scale dimensiond of the scale and chiral-symmetry-breaking partu of the strong-interaction Hamiltonian density by using the Fubini-Furlan extrapolation procedure and the available experimental information on thes-wave,I=0, π-π phase shifts and scattering lengths. We obtain 2.3<d<3.0.

Riassunto

Si fa una stima della dimensione di scaled della trasformazione di scala e della parteu che rompe la simmetria chirale della densità hamiltoniana dell’interazione forte, usando la procedura di estrapolazione di Fubini e Furlan e le informazioni sperimentali disponibili, gli spostamenti di fase e le lunghezze di scattering π-π,I=0, di ondas. Si ottiene 2.3<d<3.0.

Реэюме

Мы оцениваем раэмер масщтабаd для частиu, характериэуюшей нарущение масщтабной и киральной симметрии, для плотности Гамильтониана сильного вэаимодействия, испольэуя зкстраполяционную процедуру Фубини-Фурлана и имеюшуюся зкспериментальную информацию для "-волновых,I=0, π-π фаэовых сдвигов и длин рассеяния. Мы получаем 2.3<d<3.0.
