TL;DR: In this article, a search for lepton flavour violating decays of the Higgs boson in the mu tau and e tau decay modes is presented, based on a data set corresponding to an integrated luminosity of 35.9 fb(-1) of proton-proton collisions collected with the CMS detector in 2016, at a centre-of-mass energy of 13 TeV.
Abstract: A search for lepton flavour violating decays of the Higgs boson in the mu tau and e tau decay modes is presented. The search is based on a data set corresponding to an integrated luminosity of 35.9 fb(-1) of proton-proton collisions collected with the CMS detector in 2016, at a centre-of-mass energy of 13 TeV. No significant excess over the standard model expectation is observed. The observed (expected) upper limits on the lepton flavour violating branching fractions of the Higgs boson are B(H -> mu tau) e tau) < 0.61% (0.37%), at 95% confidence level. These results are used to derive upper limits on the off-diagonal mu tau and e tau Yukawa couplings root vertical bar Y-mu tau vertical bar(2) + vertical bar Y-mu tau vertical bar(2) < 1.43 x 10(-3) and root vertical bar Y-e tau vertical bar(2) + vertical bar Y-tau e vertical bar(2) < 2.26 x 10(-3) at 95% confidence level. The limits on the lepton flavour violating branching fractions of the Higgs boson and on the associated Yukawa couplings are the most stringent to date.

TL;DR: The structure of the cationic (non H+) light-driven pump at physiological pH in its pentameric form provides new insights into the mechanisms of microbial rhodopsins and opens the way to a rational design of novel cation pumps for optogenetics.
Abstract: Rhodopsins are the most universal biological light-energy transducers and abundant phototrophic mechanisms that evolved on Earth and have a remarkable diversity and potential for biotechnological applications. Recently, the first sodium-pumping rhodopsin KR2 from Krokinobacter eikastus was discovered and characterized. However, the existing structures of KR2 are contradictory, and the mechanism of Na+ pumping is not yet understood. Here, we present a structure of the cationic (non H+) light-driven pump at physiological pH in its pentameric form. We also present 13 atomic structures and functional data on the KR2 and its mutants, including potassium pumps, which show that oligomerization of the microbial rhodopsin is obligatory for its biological function. The studies reveal the structure of KR2 at nonphysiological low pH where it acts as a proton pump. The structure provides new insights into the mechanisms of microbial rhodopsins and opens the way to a rational design of novel cation pumps for optogenetics.

TL;DR: In this article, a search for heavy resonances that decay to tau lepton pairs is performed using proton-proton collisions at square root(s) = 13 TeV.
Abstract: A search for heavy resonances that decay to tau lepton pairs is performed using proton-proton collisions at sqrt(s) = 13 TeV. The data were collected with the CMS detector at the CERN LHC and correspond to an integrated luminosity of 2.2 inverse femtobarns. The observations are in agreement with standard model predictions. An upper limit at 95% confidence level on the product of the production cross section and branching fraction into tau lepton pairs is calculated as a function of the resonance mass. For the sequential standard model, the presence of Z' bosons decaying into tau lepton pairs is excluded for Z' masses below 2.1 TeV, extending previous limits for this final state. For the topcolor-assisted technicolor model, which predicts Z' bosons that preferentially couple to third-generation fermions, Z' masses below 1.7 TeV are excluded, representing the most stringent limit to date.

TL;DR: The use of the SHR is demonstrated as a highly efficient nonlinear optical element for: (i) the generation of the third harmonic from a single SHR; (ii) the excitation of intense multiphoton luminescence from asingle SHR.
Abstract: We realize giant optical nonlinearity of a single plasmonic nanostructure which we call a split hole resonator (SHR). The SHR is the marriage of two basic elements of nanoplasmonics, a nanohole and a nanorod. A peak field intensity in the SHR occurs at the single tip of the nanorod inside the nanohole. The peak field is much stronger than those of the nanorod and nanohole, because the SHR field involves contributions from the following two field-enhancement mechanisms: (1) the excitation of surface plasmon resonances and (2) the lightning-rod effect. Here, we demonstrate the use of the SHR as a highly efficient nonlinear optical element for: (i) the generation of the third harmonic from a single SHR; (ii) the excitation of intense multiphoton luminescence from a single SHR.
