As. Sakharov et al., CONTRIBUTION OF HORIZONTAL INTERACTION TO THE MASS DIFFERENCE OF NEUTRAL MESONS, Physics of atomic nuclei, 59(11), 1996, pp. 1967-1971
The contributions of horizontal-gauge-boson exchanges to the mass diff
erence of neutral mesons are considered in the model of horizontal uni
fication. It is shown that horizontal interaction may contribute signi
ficantly to the transitions <(K)over bar (0)>reversible arrow K-0 and
<(D)over bar (0)>reversible arrow D-0. The possible versions of the sc
alar sector of the model are constrained on the basis of available exp
erimental data.
