Title: ON THE MASS SPECTRA OF THE PSEUDOSCALAR MESONS IN THE RELATIVISTIC INDEPENDENT QUARK MODEL
Abstract:In the framework of the relativistic independent quark model with the QCD-motivated static potential, the masses of the ground states of pseudoscalar mesons and their radial excitations are calculated...In the framework of the relativistic independent quark model with the QCD-motivated static potential, the masses of the ground states of pseudoscalar mesons and their radial excitations are calculated for both observed mesons and unobserved ones. The strength of the spinAspin interaction and the magnitude of the meaneld contribution are estimated for both the light and heavy 0 −+ mesons. The calculated masses are in agreement with experimental values within an accuracy of 30 ÷ 40 MeV, and the predictions are obtained for the mass values of a number of unobserved yet radial excitations of pseudoscalar mesons. ‚ · ³± I ·¥²OE¨¢¨¸E¸±µ° ³µ¤¥²¨ ´¥§ ¢¨¸¨³OI ±¢ ·±µ¢ ¸ S•-³µE¨¢¨·µ¢ ´´O³ ¸E E¨I¥¸±¨³ ¶µE¥´I¨ ²µ³ ¢OI¨¸²¥´O ³ ¸¸O µ¸´µ¢´OI ¸µ¸EµO´¨° ¶¸¥¢¤µ¸± ²O·´OI ³¥§µ´µ¢ ¨ ¨I · ¤¨ ²O´OI ¢µ§iE|¤¥´¨° ± ± ¤²O ¨§¢¥¸E´OI, E ± ¨ ¤²O ´¥¨§¢¥¸E´OI ¥Ð¥ ¸µ¸EµO´¨°. �I¥´¥´O ¢¥²¨I¨´ ¸¶¨´- ¸¶¨´µ¢µ£µ ¢§ ¨³µ¤¥°¸E¢¨O ¨ §´ I¥´¨¥ ¢±² ¤ ¸·¥¤´¥£µ ¶µ²O ¤²O ²¥£±¨I ¨ ¤²O EO|¥²OI 0 −+ -³¥§µ´µ¢. ‚OI¨¸²¥´´O¥ ³ ¸¸O ¸µ£² ¸EOE¸O ¸ O±¸¶¥·¨³¥´E ²O´O³¨ §´ I¥´¨O³¨ ¸ ¶µ£·¥I´µ¸EOO 30 ÷ 40 ŒO‚. �µ²EI¥´O E ±|¥ ¶·¥¤¸± § ´¨O §´ I¥´¨° ³ ¸¸ ¤²O · O¤ ´¥ µE±·OEOI ¶µ± · ¤¨ ²O´OI ¢µ§iE|¤¥´¨° ¶¸¥¢¤µ¸± ²O·´OI ³¥§µ´µ¢.Read More
