We add Dark Matter Dark Energy terms with a quintessence field interacting with a Dark Matter field to a MSSM EW Lagrangian previously used to calculate the magnetic field created during the EWPT. From the expectation value of the quintessence field we estimate the Dark Matter mass for parameters used in previous work on Dark Matter-Dark Energy interactions.
Using a 3 + 1 neutrino model with one sterile and the three standard active neutrinos with a 4x4 unitary transformation matrix, U, relating flavor to mass neutrino states, the probability of $ν_μ$ to $ν_e$ transition is estimated using sterile-active neutrino masses determined by MiniBooNE and other experiments and sterile-active neutrino angles in the 4x4 U matrix.
The energies of neutrinos in a neutrinosphere, the dense matter created after the gravitational collapse of a massive star, are estimated. Cubic equations for energy eigenvalues of neutrinos are used, with the effective masses found by taking the neutrinos at rest in neutrinosphere matter. Large differences in the effective mass of some neutrino species in a neutrinosphere compared to vacuum are found.
This is an extension of recent studies [arXiv:1207.3296] for $Υ(nS)$ and $Ψ(1S,2S)$ production at the LHC in pp collisions, $\sqrt{s}$=7.0 GeV, with the ALICE detector.
We review recent research in neutrino physics, including neutrino oscillations to test time reversal and CP symmetry violations, the measurement of parameters in the U matrix, sterile neutrino emission causing pulsar kicks, and neutrino energies in the neutrinosphere.
This is a continuation of recent studies of $Υ(nS)$ production at the LHC in pp collisions. Our previous studies were for rapidity y=-1 to 1 for the CMS detector, while the present study is for y=2.5 to 4.0 at the LHC.
We estimate the relative probabilities of $Ψ'(2S)$ to $J/Ψ$ production at BNL-RHIC and $Υ(nS)$ production at the LHC and Fermilab in p-p collisions, using our recent theory of mixed heavy quark hybrids, in which the $Ψ'(2S)$ and $Υ(3S)$ mesons have approximately equal normal $q\bar{q}$ and hybrid $q\bar{q}g$ components.
We calculate the momentum given to a proto neutron star during the first 10 seconds after temperature equilibrium is reached, using recent evidence of sterile neutrinos and a measurement of the mixing angle. This is a continuation of an earlier estimate with a wide range of possible mixing angles. Using the new mixing angle we find that sterile neutrinos can account for the observed pulsar velocities.
Measurements of CP violation (CPV) and the basic $δ_{CP}$ parameter are the goals of the LBNE Project, which is being planned. Using the expected energy and baseline parameters for the LBNE Project, CPV and the dependence of CPV on $δ_{CP}$ are estimated, to help in the planning of this project.
We introduce the quark virtuality distribution [$λ^{2}_{q}(x)$] as an extenson of the quark virtuality by using nonlocal rather than local quark vacuum condensates. Our results show that the quark virtuality distribution decreases gradually from a finite value to zero as $x$ increases. This clearly indicates that quarks are confined inside hadrons, whereas, as $x$ approaches zero quarks have a finite virtuality, which shows asymptotic freedom of quarks in QCD. The present predictions are important not only for studying the properties of QCD vacuum states, and non-perturbative QCD problems, but also for study of the cosmological constant problem, which we have shown should be treated using nonlocal quark vacuum condensate in the Ghost theory of QCD.
We suggested a new experiment for the MINOS project, with baseline L=735 km, to employ another detector at baseline 2L, which could measure TRV, as with a 10% e-mu conversion at distance L. There would be a 1% increase of the original flavor at 2L, which could be detected.
Based on the Veneziano ghost theory of QCD, we estimate the cosmological constant $Λ$, which is related to the vacuum energy density, $ρ_Λ$, by $Λ= 8πG ρ_Λ$. In the recent Veneziano ghost theory $ρ_Λ$ is given by the absolute value of the product of the local quark condensate and quark current mass:$ρ_Λ = \frac{2N_{f}H}{m_{η'}}c |m_{q}<0|:\bar{q}q:|0>|$. By solving Dyson-Schwinger Equations for a dressed quark propagator, we found the local quark condensate $<0|:\bar{q}q:|0> \simeq -(235 MeV)^{3}$, the generally accepted value. The quark current mass is $m_{q} \simeq$ 4.0 Mev. This gives the same result for $ρ_Λ$ as found by previous authors, which is somewhat larger than the observed value. However, when we make use of the nonlocal quark condensate, $<0|:\bar{q}(x)q(0):|0>= g(x)<0|:\bar{q}q:|0>$, with g(x) estimated from our previous work, we find $Λ$ is in a good agreement with the observations.
We estimate the dependence of $ν_μ$ to $ν_{e}$ conversion on parameters $θ_{13}$ and $δ_{CP}$ for several experimental facilities studying neutrino oscillations. We use the S-Matrix theory to estimate $\bar{ν_e}$ disappearance and compare estimates based on an older theory being used to extract $θ_{13}$ from the Double Chooz, Daya Bay, and RENO data, to assist in extracting an accurate value for $θ_{13}$ from these projects. We use values of $θ_{13}$ within known limits, and estimate the dependence of $ν_μ$ - $ν_{e}$ CP violation (CPV) probability on $δ_{CP}$ in order to suggest new experiments to measure CPV for neutrinos moving in matter.
This is an extension of the L-2L experiment for measurement of time reversal violation (TRV) proposed in a recent publication. The main new aspects are taking into account the curvature of the earth's surface for long baseline neutrino beams, and recognizing that the matter effects disappear when the baseline is extended. A slight modification of the MINOS project, with a new detector at 2L, is proposed.
This is a continuation of recent studies of $Υ(nS)$ production at the LHC in p-p collisions. Our previous studies were for 2.76 TeV, while the present predictions are for 7.0 TeV collisions.
We estimate CP violation for several experimental facilities studying neutrino oscillations. We also estimate the probability of $ν_μ$ to $ν_{e}$ conversion, using values of the parameter $θ_{13}$ within the known limits, in order to suggest new experiments to measure CP violation for neutrinos moving in matter.
We estimate the time reversal violations for neutrino oscillations in matter for typical experimental energies and baselines. We examine the present status of experiments on neutrino oscillations, propose experiments for TRV, and discuss the future.
We estimate the relative branching ratio of $σ$ to 2$π$ for the decay of the $Ψ'(2S)$, which we have found to be a mixed charm and hybrid charmonium meson. The external field method and correlators from a previous calculation are used to estimate these decays. We find the $σ$ to 2$π$ branching ratio for $Ψ'(2S)$ to the $J/Ψ(1S)$ decay to be 0.98, in agreement with an experiment at IHEP-BES.
