Abstract: The new experimentally evidenced neutral boson of 34 me, supposed to be an X-boson of a fifth basic force, was predicted as being a basic z0 preon of cold formed quarks by a pre-quantum model of elementary particle resulted from an etherono-quantonic theory of the author, and can be a strong argument for a Bose-Einstein condensate model of particle, resulted by magnetically confined gammons formed as pairs of quasielectrons. In the paper are brought arguments in the favour of the preonic structure of quarks and for the cold genesis of the elementary particles and is proposed a pre-quantum model of quark, resulted as cluster of quasi-electrons. The brought arguments sustain also the conclusion that the z0 boson can be a “dark matter” constituent.Abstract: The new experimentally evidenced neutral boson of 34 me, supposed to be an X-boson of a fifth basic force, was predicted as being a basic z0 preon of cold formed quarks by a pre-quantum model of elementary particle resulted from an etherono-quantonic theory of the author, and can be a strong argument for a Bose-Einstein condensate model of particle...Show More
