It is supposed that the mass of the antiparticles is negative and this is used to explain the observed value of the cosmological constant. For simplicity are considered only electrons and positrons. It is obtained a value near to that observed. If this is taken as the dark energy, it constitutes an explanation of the accelerating expansion of the u...

Commonly the mass of positron is said to be positive, as the electron mass. But is it true? The Dirac equation is valid also for particles of negative mass. In this article it is supposed that the positron has a negative gravitational mass, but positive inertial mass. Possible consequences are examined and a way to see the right sign of the mass is...

This article tries to shed more light on the radiation reaction force, a critical outstanding problem. Is used an experimental result, the Compton Effect, to obtain the Larmor formula. In this way is seen from where comes the radiated energy. Therefore is possible to obtain an expression for the reaction force that is coherent and does not have...

It is suggested how to get more information on the relationship between charge and mass and how to investigate the electromagnetic field values of charged particles at very short distances.

It is described a way to investigate pairs production at the moment of formation. It is obtained at which reciprocal distance the two particles emerge from void.

In my opinion, the problem of radiation reaction force cannot be solved in a satisfactory way because it is not contained in the premises. Is like to want a fruit after without having the seed before. The formulas about the electromagnetic four-momentum derive from the Lorentz force, which is obtained experimentally by measuring the electromagnetic...

It is shown that a charge doesn't radiate in his rest frame; radiates in other frames if the acceleration is not constant.

In this article it is shown that a radiating charge moving in a constant uniform magnetic field has an approximated trajectory that copies an Euler spiral. This is a simple result that connects a particle that moves in a spiral to a car entering a highway, a surprising, but not too much, result, considering the nature is smart. It adds itself to th...

It is shown that the Lorentz contraction of rods in motion is only apparent, due to the way in which the units of length in the two reference systems in relative motion are chosen. The space does not contract in the direction of motion. Appears so because are changed the units of measure and the measures are made at instants of time different at bo...

It is shown that a charged particle without mass must have a purely electromagnetic mass due to radiation reaction force not in nite and is devised a new way to measure it. It is suggest to use pair production to investigate charged particles elds at very short distances.

Ab initio quantum calculations are presented for the H+-H2 system at several collision energies. The correct close-coupling (CC) equations are solved within the energy-corrected rigid-rotor (ECRR) approximation for the target molecule, and inelastic integral and differential cross sections between low rotational levels are thus obtained. The releva...

An an initio computed potential surface for the H3+ system at various geometries is expanded in Legendre polynomials and the ensuing radial coefficients are employed to yield the S-matrix elements from the close coupling expansion of the scattering equations, at the collision energy of recently performed molecular beam experiments. The rotationally...
