On the Possibility of the Formation of Particles with a Nonzero Rest Mass in the “Gas” of Null-strings

摘要

A solution of the Einstein equations for a multi-string system having a layered structure is found. It is shown that the influence of the gravitational field of such a multi-string system can lead to stable in time oscillations of the test null-string in the vicinity of fixed point of space. This situation can be interpreted as a particle localized in space with an effective nonzero rest mass.
