Word of the editor. |


Theoretical Physics Letters (TPL) An SCI & SCOPUS -indexed monthly thrice peer-reviewed journal. TPL is an partial open access international journal which covers the recent trends in theoretical, experimental and observational physics. This aims to provide a great opportunity to the lead researchers worldwide for publishing their valuable works at a minimum honorarium. Because I believe that great ideas are priceless. TPL journal is an international, peer-reviewed, partial open-access journal on theoretical, applied physics, science and its applications published monthly online by Physics Tomorrow Letters.

The Nature of the 1 MeV-Gamma quantum in a Classic Interpretation of the Quantum Potential

By considering wave-particle dualism with an interpretation of the squared amplitude of the wave function R2(Y) compatible with the known Bohm’s equations, for a 1 MeV-gamma-quantum considered as ‘gammonic’ (e-e+)- pair of electrons having the phase speed of the associated wave equal to the group speed of passing through a low frictional component of the quantum vacuum, it results a value of the quantum potential Q equal to the particle’s kinetic energy, Qc = ½mv2 , for a classic model of electron composed by heavy photons, this value being explained by a generalized relation of quantum equilibrium of de Broglie type, with the associated entropy proportional to its action S, as representing a centrifugal potential given by a spinorial mass ms = nvmv » me resulting by nv -vector photons explaining also a half of the electron’s rest energy by considering and a dynamic component of the quantum vacuum- given by quantum and sub-quantum winds ............

Dirac-Majorana neutrino type conversion induced by an oscillating scalar dark matter

Some properties of a neutrino may differ significantly depending on whether it is Dirac or Majorana type. The type is determined by the relative size of Dirac and Majorana masses, which may vary if they arise from an oscillating scalar dark matter.

Calculation of the Hubble Constant, the Minimum Mass, and the Proton Charge Radius Using the Dirac’s Hypothesis on the Ratio of the Electrostatic Force to the Gravitational Force

This publication suggests that some physical values could be calculated using the Dirac’s hypothesis on the observed ratio of the electrostatic force to the gravitational force. The calculated value of the Hubble constant is H ≈ 72.013 km s‑1 Mpc‑1 and that of the minimum mass, Mmin ≈ 1.720 6 × 10‑68 kg. Recent observations suggest that the proton charge radius could also be calculated using an additional but related assumption: rp ≈ 0.826 4 fm.
