“…There are recently different constraints for the sum of neutrino mass such as the updated bounds in Ref.

We propose an extended 2HDM with Q 6 × Z 4 × Z 2 symmetry that can interpret the SM fermion mass hierarchy and their mixing patterns with the Dirac CP phase in the framework of the type-I seesaw mechanism. The smallness of neutrino masses is obtained via the Type-I seesaw mechanism. Both normal and inverted neutrino mass hierarchies are consistent with the experimental data on the lepton and quark masses and mixing patterns. The prediction for the Dirac phase is δ CP ∈ (1.50, 1.82)π for normal ordering and δ CP ∈ (1.50, 1.80)π for inverted ordering that includes its experimentally maximum value. The sum of neutrino masses is predicted to be m i ∈ (58.50, 60.50) meV for normal ordering and m i ∈ (98.50, 101.00) meV for inverted ordering which are well consistent with all the recent limits. In addition, the predictions for the effective neutrino masses are m ee ∈ (3.70, 3.90)meV for normal ordering and m ee ∈ (48.00, 49.40) meV for inverted ordering which are in

“…The notion that d ′′ is nonzero might associate with a notion of anomalous mass and with the solutionpair 2g1`3`4 (which associates with the Z boson via Γ = 1'3'4 and with 2g).

Physics lacks a confirmed description of dark matter, has yet to develop an adequate understanding of dark energy, and includes unverified conjectures regarding new elementary particles. This essay features modeling that addresses those problems and explains otherwise unexplained data. Our modeling starts from five bases – multipole expansions for the electromagnetic and gravitational fields associated with an object, the list of known elementary particles, some aspects of mathematics for isotropic harmonic oscillators, concordance cosmology, and a conjecture that the universe includes six isomers of most elementary particles. The multipole expansions – which have use in conjunction with Newtonian kinematics modeling, special relativity, and general relativity – lead to a catalog of kinematics properties such as charge, magnetic moment, mass, and repulsive gravitational pressure. The multipole expansions also point to all known elementary particles, some properties of those particles, and properties of some would-be elementary bosons and elementary fermions. The harmonic-oscillator mathematics points to Gauge symmetries regarding some elementary bosons. The would-be elementary fermions lack charge and would measure as dark matter. The conjecture regarding six isomers of most elementary particles rounds out and dominates our specification for dark matter. Five of the isomers form the basis for most dark matter. Our modeling explains ranges of observed ratios of dark matter effects to ordinary matter effects – for the universe, galaxy clusters, two sets of galaxies observed at high redshifts, three sets of galaxies observed at modest redshifts, and one type of depletion of cosmic microwave background radiation. Our description of repulsive gravitational pressure points toward resolution for tensions – between data and modeling – regarding the recent rate of expansion of the universe, resolution for possible tensions regarding large-scale clumping, and resolution for possible tensions regarding interactions between neighboring galaxies. Our work regarding gravity, dark matter, and elementary particles suggests characterizations for eras that might precede the inflationary epoch, a mechanism that might have produced baryon asymmetry, mechanisms that govern the rate of expansion of the universe, and insight about galaxy formation and evolution.

“…Recently, the methods of Effective Field Theory (EFT) for large scale structure formation [21][22][23][24][25] built on Perturbation Theory (PT) [26] have reached sufficient maturity to be used to compare the galaxy power spectrum (as well as other statistics) of real survey data directly to the analytical modeling of non-linearities [27,28]; see also [29][30][31][32][33][34][35][36][37][38]. These full-shape analyses capture at the same time the BAO and the redshift space distortions (RSD) features, reaching similar constrictive power as Planck experiment for some cosmological parameters.…”

Fast computation of non-linear power spectrum in cosmologies with massive neutrinos

We compute 1-loop corrections to the redshift space galaxy power spectrum in cosmologies containing additional scales, and hence kernels different from Einstein-de Sitter (EdS). Specifically, our method is tailored for cosmologies in the presence of massive neutrinos and some modified gravity models; in this article we concentrate on the former case. The perturbative kernels have contributions that we notice appear either from the logarithmic growth factor f (k, t), which is scale-dependent because of the neutrino free-streaming, or from the failure of the commonly used approximation f 2 = Ω m . The latter contributions make the computation of loop corrections quite slow, precluding full-shape analyses for parameter estimation. However, we identify that the dominant pieces of the kernels come from the growth factor, allowing us to simplify the kernels but retaining the characteristic free-streaming scale introduced by the neutrinos' mass. Moreover, with this simplification one can exploit FFTLog methods to speed up the computations even more. We validate our analytical modeling and numerical method with halo catalogs extracted from the Quijote simulations finding good agreement with the, a priori, known cosmological parameters. We make public our Python code FOLPSν to compute the redshift space power spectrum in a fraction of second. Code available at https://github.com/henoriega/FOLPS-nu.
