A 34 m e NEUTRAL BOSON, PREDICTED BY A PARTICLES COLD GENESIS THEORY AND EXPERIMENTALLY EVIDENCED, AS ARGUMENT FOR A PREONIC QUARK MODEL BY MARIUS ARGHIRESCU * *State Office for Inventionsand Trademarks, OSIM, RO Abstract: The new neutral boson of 34 m e , experimentally evidenced and supposed to be an X-boson of a fifth basic force, was predicted as being a basic z 0 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. An argument in the favour of the preonic structure of quarks and for the Cold Genesis of the elementary particles is proposed a new, pre-quantum model of quark resulted in theory with quasi-crystallin as structure of quasi-electrons of the basic preon z 0 . The brought arguments sustain also the conclusion that the z 0 boson can be a „dark matter” constituent. Key words: pre-quantum model, neutral boson, preon, quark model, B-E condensate, dark matter, X boson. 1. Introduction In a relative recent paper, [1], a research team of Science’s Institute for Nuclear Research in Debrecen, Hungary, after some experiments for the detection of dark photons, announced that significant deviation from the internal pair creation during the (e + -e - ) transition to the ground state of an excited Be8* nucleus was observed at large angles, which indicates that, in an intermediate step, was formed a neutral super-light particle with a mass of 17 MeV/c 2 , (34 m e ), the excited Be8* state being obtained by proton interaction with a target of Li7, i.e. by a reaction of type: Li7 + p + Be*Be8 + b 0 ; b 0  e + + e - , (1) In another paper, [2], a team of american physicists from California concluded that the evidenced new boson is not a dark photon and this experimental result could be the evidence for a fifth fundamental force mediated by the predicted X-boson, coupling quarks with leptons, which decay by a reaction of type: X → e + + e - or X → +(neglijible), instead: X → u + u ; X → e+ +d. Later, the considered X boson was theoretically identified as k = 113 light pion, by the p-Adic thermodynamics, [3]. But a particle with the same mass: 34 m e , was considered by a cold genesis quark model as being the basic preon by which is composed the effective quark mass, according to a cold genesis pre- quantum theory of particles and fields of the author, (CGT), [4-6]. According to this theory, based on the galileian relativity, the magnetic field is generated by an etherono-quantonic vortex  M =  A +   of s-etherons (sinergons-with mass m s  10 -60 kg)- giving the magnetic potential A by an impulse density: p s (r)=( s c) r and of quantons (h-quanta, with mass: m h = h/c 2  7.37x10 -51 kg), giving the magnetic moment and the magnetic induction B by an impulse density: p c (r)= ( c v c ) r , generated by a magnetic moment of an atomic particle but also by a magnet or an electromagnet. The theory deduces also a variation of the Compton radius and of the fermion’s magnetic moment, inverse proportional with the density in which is placed the particle’s super -dense kernel, (the particle’s centroid) and sustains the possibility of a cold genesis of particles, which results theoretically in a chiral soliton model as Bose-Einstein condensate of photons- in the electron’s case and of “gammons”μ  c = (e + –e - ) - considered as pairs of degenerate electrons, i.e- of quasielectrons- in
