We show that the characteristic sizes of astrophysical and cosmological structures, where gravity is the only overall relevant interaction assembling the system, have a phenomenological relation to the microscopic scales whose order of magnitude is essentially ruled by the Compton wavelength of the proton. This result agrees with the absence of screening mechanisms for the gravitational interac...

An inclusive search for long-lived exotic particles decaying to a pair of muons is presented. The uses data collected by the CMS experiment at CERN LHC in proton-proton collisions $\sqrt{s}$ = 13 TeV 2016 and 2018 corresponding an integrated luminosity 97.6 fb$^{-1}$. experimental signature oppositely charged originating from common secondary vertex spatially separated pp interaction point dist...

We implement a three-body confinement force, introduced on an algebraic basis, into a semirelativistic version of the Goldstone-boson-exchange constituent quark model. By solving the Faddeev equations we show that this interaction can increase the gap between singlet and colour states, such as the latter can be ignored. We present results for a ∆and a Y-shape threebody interaction in terms of t...

We study the possible relationship between the saturation properties of nuclear matter and the inclusion of non-locality in the nucleon-nucleon interaction. To this purpose we compute the saturation curve of nuclear matter within the Bethe-Brueckner-Goldstone theory using a recently proposed realistic non-local potential, and compare it with the corresponding curves obtained with a purely local...

In absence of the Standard Model Higgs boson the interaction among the gauge bosons becomes strong at high energies (∼ 1TeV) and influences the couplings between them. Each trilinear and quartic gauge boson vertex is characterized by a set of couplings which are expected to deviate from their Standard Model values already at energies lower than the energy scale of the New Physics. The precise m...

Abstract We discuss an equilibrium mean-field properties of mixtures consisting bosons and spin-polarized fermionic atoms with a point-like interaction in arbitrary dimension 2 < d 4 . Particularly, besides t...

The hypothesis is explored that fermion rest mass is due entirely to self-interaction via virtual excitation of gauge bosons. This requires revising the standard model to treat both chiral projections of a fermion field as SU(2) doublets, which precludes Yukawa coupling to a scalar (Higgs) boson field. The estimated self-interaction mass of the electron neutrino is 0.291× 10−5me. The implied se...

The study focuses on exploring the changes in hyperon-baryon interaction at various nuclear densities. This approach starts by building a vacuum hyperon-nucleon model based Boson -Exchange maintaining SU(3) flavor symmetry. Bethe-Goldstone equation is then explored to investigate medium properties over bare interaction. A detailed investigation of density dependence revealed clear low energy pa...

Generalized spin-boson (GSB) models describe the interaction between a quantum mechanical system and structured boson environment, mediated by family of coupling functions known as form factors. We propose an extension class GSB which can accommodate non-normalizable factors, provided that they satisfy weaker growth constraint, thus accounting for rigorous description wider range physical scena...

Based on chiral dynamics, existence of exotic hadrons is discussed in the SU(3) symmetric limit. The low energy s-wave interaction of the Nambu-Goldstone boson with a hadron is known to be determined model-independently, which has been used to generate some hadron resonances in nonexotic channels. We show that this interaction in any exotic channels is not strong enough to generate a bound stat...
