This Letter presents a search for new physics manifested as anomalous triple gauge boson couplings in WW and WZ diboson production in proton-proton collisions. The search is performed using events containing a W boson that decays leptonically and a W or Zboson whose decay products are merged into a single reconstructed jet. The data, collected at root s= 8TeVwith the CMS detector at the LHC, correspond to an integrated luminosity of 19 fb(-1). No evidence for anomalous triple gauge couplings is found and the following 95% confidence level limits are set on their values: lambda([-0.011, 0.011]), Delta(kappa gamma)([-0.044, 0.063]), and Delta g(1)(Z)([-0.0087, 0.024]). These limits are also translated into their effective field theory equivalents: c(WWW)/Lambda(2)([- 2.7, 2.7] TeV-2), c(B)/Lambda(2)([-14, 17] TeV-2), and cW/Lambda(2)([- 2.0, 5.7] TeV-2).

We report on the first γ-ray spectroscopy of low-lying states in neutron-rich Kr98,100 isotopes obtained from Rb99,101(p,2p) reactions at ∼220 MeV/nucleon. A reduction of the 21+ state energies beyond N=60 demonstrates a significant increase of deformation, shifted in neutron number compared to the sharper transition observed in strontium and zirconium isotopes. state-of-the-art beyond-mean-field calculations using the Gogny D1S interaction predict level energies in good agreement with experimental results. The identification of a low-lying (02+, 22+) state in Kr98 provides the first experimental evidence of a competing configuration at low energy in neutron-rich krypton isotopes consistent with the oblate-prolate shape coexistence picture suggested by theory.

In-beam γ-ray spectroscopy of Cu79 is performed at the Radioactive Isotope Beam Factory of RIKEN. The nucleus of interest is produced through proton knockout from a Zn80 beam at 270 MeV/nucleon. The level scheme up to 4.6 MeV is established for the first time and the results are compared to Monte Carlo shell-model calculations. We do not observe significant knockout feeding to the excited states below 2.2 MeV, which indicates that the Z=28 gap at N=50 remains large. The results show that the Cu79 nucleus can be described in terms of a valence proton outside a Ni78 core, implying the magic character of the latter.

We report on the measurement of the first 2+ and 4+ states of Cr66 and Fe70,72 via in-beam γ-ray spectroscopy. The nuclei of interest were produced by (p,2p) reactions at incident energies of 260 MeV/nucleon. The experiment was performed at the Radioactive Isotope Beam Factory, RIKEN, using the DALI 2γ-ray detector array and the novel MINOS device, a thick liquid hydrogen target combined with a vertex tracker. A low-energy plateau of 21+ and 41+ energies as a function of the neutron number was observed for N≥38 and N≥40 for even-even Cr and Fe isotopes, respectively. state-of-the-art shell model calculations with a modified Lenzi-Nowacki-Poves-Sieja (LNPS) interaction in the pfg9/2d5/2 valence space reproduce the observations. Interpretation within the shell model shows an extension of the island of inversion at N=40 for more neutron-rich isotopes towards N=50.

The β-decay half-lives of 94 neutron-rich nuclei Cs144−151, Ba146−154, La148−156, Ce150−158, Pr153−160, Nd156−162, Pm159−163, Sm160−166, Eu161−168, Gd165−170, Tb166−172, Dy169−173, Ho172−175, and two isomeric states Er174m, Dy172m were measured at the Radioactive Isotope Beam Factory, providing a new experimental basis to test theoretical models. Strikingly large drops of β-decay half-lives are observed at neutron-number N=97 for Ce58, Pr59, Nd60, and Sm62, and N=105 for Eu63, Gd64, Tb65, and Dy66. Features in the data mirror the interplay between pairing effects and microscopic structure. r-process network calculations performed for a range of mass models and astrophysical conditions show that the 57 half-lives measured for the first time play an important role in shaping the abundance pattern of rare-earth elements in the solar system.

A low-lying state in In82131, the one-proton hole nucleus with respect to double magic Sn132, was observed by its γ decay to the Iπ=1/2− β-emitting isomer. We identify the new state at an excitation energy of Ex=1353 keV, which was populated both in the β decay of Cd13183 and after β-delayed neutron emission from Cd13284, as the previously unknown πp3/2 single-hole state with respect to the Sn132 core. Exploiting this crucial new experimental information, shell-model calculations were performed to study the structure of experimentally inaccessible N=82 isotones below Sn132. The results evidence a surprising absence of proton subshell closures along the chain of N=82 isotones. The consequences of this finding for the evolution of the N=82 shell gap along the r-process path are discussed.

Solid electrolytes (SEs) in all-solid-state batteries (ASSBs) are garnering considerable attention for their potential applications in next-generation energy storage systems. Amorphous SEs with dual-anion hold great promise for achieving favorable performance, such as high ionic conductivity and good compatibility with electrodes within ASSBs. Here, we discover a family of amorphous nitride-halide SEs, Li 3 x MCl y N x (M=Ta or La, 1≤3 x ≤1.4, y=5 or 3), which can achieve ionic conductivities up to 7.34 mS cm −1 at 30 °C. The amorphous properties and local structures are investigated using powder X-ray diffraction, cryogenic transmission electron microscopy, and atomic pair distribution function analysis. Impressively, ASSBs employing amorphous Li 3 x TaCl 5 N x have demonstrated good performance at high rates and charging voltages, as well as at low temperature.

Neutron-rich Se88,90,92,94 isotopes were studied via in-beam γ-ray spectroscopy after nucleon removal reactions at intermediate energies at the Radioactive Isotope Beam Factory. Based on γ−γ coincidence analysis, low-lying excitation level schemes are proposed for these nuclei, including the 21+, 41+ states and 22+ states at remarkably low energies. The low-lying 22+ states, along with other features, indicate triaxiality in these nuclei. The experimental results are in good overall agreement with self-consistent beyond-mean-field calculations based on the Gogny D1S interaction, which suggests both triaxial degree of freedom and shape coexistence playing important roles in the description of intrinsic deformations in neutron-rich Se isotopes.
