Pseudoscalar decay constants of kaon and D-mesons from Nf=2 twisted mass Lattice QCD
B. Blossier, P. Dimopoulos, R. Frezzotti +12
We present the results of a lattice QCD calculation of the pseudoscalar meson decay constants fpi, fK, fD and fDs, performed with Nf=2 dynamical fermions. The simulation is carried…
Form factors of the and semileptonic decays with twisted mass lattice QCD
S. Di Vita, B. Haas, V. Lubicz +3
We present lattice results for the vector and scalar form factors of the semileptonic decays D -> Ï\ell ν_ell and D -> K \ell ν_\ell in the physical range of values of squared f…
Revealing topological Dirac fermions at the surface of strained HgTe thin films via Quantum Hall transport spectroscopy
C. Thomas, O. Crauste, B. Haas +7
We demonstrate evidences of electronic transport via topological Dirac surface states in a thin film of strained HgTe. At high perpendicular magnetic fields, we show that the elect…
Vector and scalar form factors for K- and D-meson semileptonic decays from twisted mass fermions with Nf = 2
S. Di Vita, B. Haas, F. Mescia +3
We present lattice results for the form factors relevant in the K -> pion and D -> pion semileptonic decays, obtained from simulations with two flavors of dynamical twisted-mass fe…
Measurement and analysis of the Am-243 neutron capture cross section at the n_TOF facility at CERN
TOF Collaboration, E. Mendoza, D. Cano-Ott +129
Background:The design of new nuclear reactors and transmutation devices requires to reduce the present neutron cross section uncertainties of minor actinides. Purpose: Reduce the $…
Highly efficient spin-to-charge current conversion at room temperature in strained HgTe surface states
P. Noël, C. Thomas, Y. Fu +7
We report the observation of spin-to-charge current conversion in strained mercury telluride at room temperature, using spin pumping experiments. The conversion rates are found to…
Nonpolar m-plane GaN/AlGaN heterostructures with intersubband transitions in the 5 to 10 THz band
C. B. Lim, A. Ajay, C. Bougerol +6
This paper assesses intersubband transitions in the 1 to 10 THz frequency range in nonpolar m-plane GaN/AlGaN multi-quantum-wells deposited on free-standing semi-insulating GaN sub…
