Abstract

The first part of the paper is devoted to applying the confinement mechanism proposed earlier by the author to estimate the possible parameters of the confining SU(3) -gluonic field in neutral kaons. The estimates obtained are consistent with the widths of the electromagnetic decays K ⁰, 2 too. The corresponding estimates of the gluon concentrations, electric and magnetic colour field strengths are also adduced for the mentioned field at the scales of the mesons under consideration. The second part of the paper takes into account the results obtained previously by the author to estimate the purely gluonic contribution to the masses of all the mesons of the pseudoscalar nonet and also to consider a possible relation with a phenomenological string-like picture of confinement. Finally, the problem of masses in particle physics is shortly discussed within the framework of the approach to the chiral symmetry breaking in quantum chromodynamics (QCD) proposed recently by the author.
