TL;DR: The X-ray crystal structures of the gC1q domain of a few members of the C1q family reveal a compact jelly-roll beta-sandwich fold similar to that of the multifunctional tumor necrosis factor (TNF) ligand family, hence the C 1q and TNF superfamily.

TL;DR: In this article, the authors presented an analysis on the total width of the recently discovered Higgs boson, Gamma[H], using its relative on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays to an electron or muon pair, and the other to a neutrino pair.

TL;DR: In this article, the polarization dependence of the Raman spectra of epitaxial thin films was analyzed and the corresponding types of atomic motions as well as their expected frequency range were determined by comparison to the predictions of lattice dynamical calculations.
Abstract: The Raman spectra of epitaxial thin films of ${\mathrm{La}}_{2}\mathrm{Co}\mathrm{Mn}{\mathrm{O}}_{6}$ on (001)-oriented $\mathrm{Sr}\mathrm{Ti}{\mathrm{O}}_{3}$ substrates have been measured in several exact scattering configuration between 12 and $890\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. The polarization dependence of the spectra provide clear evidence for ordered $P{12}_{1}∕n1$ structure, differing from its parent $Fm\overline{3}m$ structure by the presence of rotational distortions. The correlation between the phonon modes in $Fm\overline{3}m$, $R\overline{3}$, and $P{12}_{1}∕n1$ phases is analyzed and the corresponding types of atomic motions as well as their expected frequency range are determined by comparison to the predictions of lattice dynamical calculations. The ferromagnetic ordering and spin-phonon coupling below ${T}_{C}$ result in softening of some of the phonon modes. The evolution of the Raman spectra at high temperatures shows no indication for $P{12}_{1}∕n1--R\overline{3}$ transition up to $800\phantom{\rule{0.3em}{0ex}}\mathrm{K}$.

TL;DR: NA62 as mentioned in this paper is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays, such as the branching fraction of the K+ → π+ ν bar nu decay, which can bring significant insights into new physics processes when comparison is made with precise theoretical predictions.
Abstract: NA62 is a fixed-target experiment at the CERN SPS dedicated to measurements of rare kaon decays. Such measurements, like the branching fraction of the K+ → π+ ν bar nu decay, have the potential to bring significant insights into new physics processes when comparison is made with precise theoretical predictions. For this purpose, innovative techniques have been developed, in particular, in the domain of low-mass tracking devices. Detector construction spanned several years from 2009 to 2014. The collaboration started detector commissioning in 2014 and will collect data until the end of 2018. The beam line and detector components are described together with their early performance obtained from 2014 and 2015 data.
