“…The effective QED constant, α em , is known [18,19,20,21,22] to increase with rising momentum transfer due to vacuum polarization (VP) effects. The VP effects can be implemented by making the fine-structure constant explicitly s-dependent (s = q 2 ):…”

on behalf of the KLOE-2 Collaboration Received Day Month Year Revised Day Month YearThe KLOE detector at the DAΦNE φ-factory has been operating in two periods from 2001 to 2006 and from 2014 to 2018 collecting a large sample of φ-meson decays. This allowed to perform precision measurements and studies of fundamental symmetries, and searches of New Physics phenomena. In this overview, the results of KLOE and KLOE-2 Collaborations are presented. The most recent results from the KLOE experiment are discussed, covering: the measurement of the running fine-structure constant αem, the Dalitz plot measurement of η → π + π − π 0 , the search of a U boson, tests of discrete symmetries and quantum decoherence.

“…It has been expanded by others [6], [9]. However, what is needed is a formula for the Planck length that is independent of G. The fine structure constant α is thought to have a logarithmic dependence on energy formed by an integral with cutoffs at high and low energies [8]. Based on the success of the Sakharov formula for G, it can be postulated that the high-energy cutoff of the logarithmic term must be the Planck scale.…”

This paper presents progress on the gravityelectromagnetism-strong (GEMS) theory in the context of a plasma universe. The GEMS theory is now understood in terms of the Standard Model of Physics and allows the practical unification of the EM, gravitational, and Strong forces. Two central problems in cosmology are addressed in the context of the GEMS theory: 1) the value of the ratio of coupling constants of EM and gravity; and 2) the calculation of the dark energy density in the cosmos, which drives cosmic expansion. It is found that a tachyonic quantum field provides the negative energy density that creates a cosmological constant. The acceleration of the cosmos is found to create a "back reaction" positive radiation pressure with a uniform spectrum out to the Planck frequency, which is a concept first proposed by Zeldovich, to partially cancel the cosmological (1.61α)), where α is the fine structure constant, is Planck's constant, c is the speed of light, and M ηc is the mass of the η cc charmonium meson. Moreover, it is found that the infrared cutoff in integrals over momentum space corresponds approximately to the 3000-MeV masses of the η cc and J/Ψ mesons that figure largely in parity violating particle events. It is also found from both derivations that GEMS predicts gravity EM unification at Planck's energy. constant. The resulting radiation field is found to provide both a mechanism for attraction of particles and production of mass via a Kaluza-Klein fifth dimension. Derivation of expressions for the gravitation constant using a combined Kaluza-Klein and Sakharov model is also shown and validated by a Standard Model Formulation based on the observed variation of α with energy

“…Free space, quantum mechanical vacuum, unified vacuum, "Dirac sea", quantum foam and topological defects with vacuum energy, virtual particles or vacuum fluctuations and decay of vacuum -all of these are entities and processes reminiscent of this stage that is the physical space. The vacuum polarization, observed experimentally [15], demonstrated that vacuum is not completely empty. The properties of quark-gluon systems also imply an existence of some vacuum structures: "… the most profound and surprising result to emerge from late twentieth-century physics may be the realization that what we perceive as empty space is in reality a highly structured and vibrant dynamical medium".…”

The nature of the physical space seems the most important subject in physics. A present paper proceeds from the assumption of physical reality of space contrary to the standard view of the space as a purely relational nonexistence -void. The space and its evolution are the primary sources of phenomena in Mega-and micro-worlds. Thus cosmology and particle physics have the same active agent -physical space.
