TL;DR: In this paper, the authors derived the value of the dark matter density at the Sun's location without globally mass-modeling the Galaxy and obtained a reliable estimate of, that, in addition has the merit of being ready to take into account any future change/improvement in the measures of the observational quantities it depends on.
Abstract: Aims. We derive the value of the dark matter density at the Sun’s location ( ) without globally mass-modeling the Galaxy. Methods. The proposed method relies on the local equation of centrifugal equilibrium and is independent of i) the shape of the dark matter density profile, ii) knowledge of the rotation curve from the galaxy center out to the virial radius, and iii) the uncertainties and the non-uniqueness of the bulge/disk/dark halo mass decomposition. Results. The result can be obtained in analytic form and it explicitly includes the dependence on the relevant observational quantities and takes their uncertainties into account. By adopting the reference, state-of-the-art values for these, we find = 0:43(11)(10) GeV/cm 3 , where the quoted uncertainties are respectively due to the uncertainty in the slope of the circular-velocity at the Sun location and the ratio between this radius and the length scale of the stellar exponential thin disk. Conclusions. We obtained a reliable estimate of , that, in addition has the merit of being ready to take into account any future change/improvement in the measures of the observational quantities it depends on.

TL;DR: The impact of primordial magnetic fields (PMFs) on the CMB temperature and polarization spectra was investigated in this paper, with different bounds depending on the specific effect that is analysed.
Abstract: We predict and investigate four types of imprint of a stochastic background of primordial magnetic fields (PMFs) on the cosmic microwave background (CMB) anisotropies: the impact of PMFs on the CMB temperature and polarization spectra, related to their contribution to cosmological perturbations; the effect on CMB polarization induced by Faraday rotation; magnetically-induced non-Gaussianities and related non-zero bispectra; and the magnetically-induced breaking of statistical isotropy. We present constraints on the amplitude of PMFs derived from different combinations of Planck data products, depending on the specific effect that is analysed. Overall, Planck data constrain the amplitude of PMFs to less than a few nanogauss, with different bounds depending on the considered model. In particular, individual limits coming from the analysis of the CMB angular power spectra, using the Planck likelihood, are B1Mpc < 4:4 nG (where B1Mpc is the comoving field amplitude at a scale of 1 Mpc) at 95 % confidence level, assuming zero helicity, and B1Mpc < 5:6 nG when we consider a maximally helical field. For nearly scaleinvariant PMFs we obtain B1Mpc < 2:1 nG and B1Mpc < 0:7 nG if the impact of PMFs on the ionization history of the Universe is included in the analysis. From the analysis of magnetically-induced non-Gaussianity we obtain three different values, corresponding to three applied methods, all below 5 nG. The constraint from the magnetically-induced passive-tensor bispectrum is B1Mpc < 2:8 nG. A search for preferred directions in the magnetically-induced passive bispectrum yields B1Mpc < 4:5 nG, whereas the the compensated-scalar bispectrum gives B1Mpc < 3 nG. The analysis of the Faraday rotation of CMB polarization by PMFs uses the Planck power spectra in EE and BB at 70 GHz and gives B1Mpc < 1380 nG. In our final analysis, we consider the harmonic-space correlations produced by Alfv´ en waves, finding no significant evidence for the presence of these waves. Together, these results comprise a comprehensive set of constraints on possible PMFs with Planck data.

TL;DR: In this article, the authors discuss the theoretical, phenomenological and experimental issues related to flavor phenomena in the charged lepton sector and in flavor conserving CP-violating processes.
Abstract: This chapter of the report of the “Flavor in the era of the LHC” Workshop discusses the theoretical, phenomenological and experimental issues related to flavor phenomena in the charged lepton sector and in flavor conserving CP-violating processes. We review the current experimental limits and the main theoretical models for the flavor structure of fundamental particles. We analyze the phenomenological consequences of the available data, setting constraints on explicit models beyond the standard model, presenting benchmarks for the discovery potential of forthcoming measurements both at the LHC and at low energy, and exploring options for possible future experiments.

TL;DR: Test d'un cadre pour the construction des pseudopotentiels separables ultra-mous proposes recemment par Vanderbilt dans le contexte des calculs de dynamique moleculaire «ab initio» de Car-Parrinello sur les atomes et les molecules.
Abstract: A scheme for the construction of ultrasoft separable pseudopotentials recently proposed by Vanderbilt is tested in the context of Car-Parrinello ab initio molecular-dynamics calculations on atoms and molecules. For the case of oxygen, the transferability of the pseudopotential is demonstrated by comparing the calculated properties of molecular ${\mathrm{O}}_{2}$ and ${\mathrm{O}}_{3}$ with those obtained from conventional approaches. Converged results are obtained using plane-wave-basis cutoffs of only \ensuremath{\sim}25 Ry. Forces can be calculated efficiently, and a molecular-dynamics simulation of molecular vibration is demonstrated.
