The results for heavy-light mesons are summarized in Table 1. The results presented here are based on the same statistical sample, consisting of 102 quenched configurations at β = 6.0 with lattice size 16 × 48, as used in our study of fB and fBs [1]. The details of the NRQCD action, the evolution equation for calculating the heavy quark propagator, the method used for setting the lattice scale,...

We have chosen the B¯0→D⁎+D¯⁎0K− reaction in order to observe I=0,JP=1+ (R1) partner state of X0(2866) stemming from D⁎K¯⁎ molecular picture. The proceeds via external emission most favored Cabibbo decay mode and one observes R1 as a very strong peak versus background D⁎+K− spectrum. branching ratio for production this is estimated 4×10−3. method used, applied B+→D−D+K+ reaction, produces signa...

We have chosen the B¯0?D?+D¯?0K? reaction in order to observe I=0,JP=1+ (R1) partner state of X0(2866) stemming from D?K¯? molecular picture. The proceeds via external emission most favored Cabibbo decay mode and one observes R1 as a very strong peak versus background D?+K? spectrum. branching ratio for production this is estimated 4×10?3. method used, applied B+?D?D+K+ reaction, produces signa...

We report the anion photoelectron spectrum of I2- taken at 5.826 eV detachment energy using velocity mapped imaging. The photoelectron spectrum exhibits bands resulting from transitions to the bound regions of the X 1Sigmag+(0g+), A' 3Piu(2u), A 3Piu(1u), and B 3Piu(0u+) electronic states as well as bands resulting from transitions to the repulsive regions of several I2 electronic states: the B...

Objectives: The current study investigated the potential acceptability and effectiveness of Contextual Intervention adapted for Autism Spectrum Disorders (CI-ASD) in developing children’s participation and mothers’ parenting self efficacy. Contextual Intervention adapted for Autism Spectrum Disorders (CI-ASD) involving contextually reflective occupational therapy combines 3 elements: parent coac...

The ACCMM model predicts the lepton spectrum from B meson decay by assuming the meson disintegrates into a spectator quark of definite mass and momentum distribution and an off shell b quark whose decay leptons (boosted into the rest frame of the meson) determine the lepton spectrum. In this letter, we show that one can define a model dependent b quark mass so that the spectrum derived from the...

We compute the continuous part of the ideal-magnetohydrodynamic (ideal-MHD) frequency spectrum of a polar mountain produced by magnetic burial on an accreting neutron star. Applying the formalism developed by Hellsten & Spies (1979), extended to include gravity, we solve the singular eigenvalue problem subject to line-tying boundary conditions. This spectrum divides into an Alfvén part and a cu...

A pioneering experiment in Λ hypernuclear spectroscopy, undertaken at the Thomas Jefferson National Accelerator Facility (Jlab), was recently reported. The experiment used the highprecision, continuous electron beam at Jlab, and a special arrangement of spectrometer magnets to measure the spectrum from C and Li targets using the (e, eK) reaction. The 12 Λ B spectrum was previously published. Th...

A measurement of the final state distribution of the (8)B β decay, obtained by implanting a (8)B beam in a double-sided silicon strip detector, is reported here. The present spectrum is consistent with a recent independent precise measurement performed by our collaboration at the IGISOL facility, Jyväskylä [O. S. Kirsebom et al., Phys. Rev. C 83, 065802 (2011)]. It shows discrepancies with prev...

Let A and B be (not necessarily unital or closed) standard operator algebras on complex Banach spaces X and Y , respectively. For a bounded linear operator A on X, the peripheral spectrum σπ(A) of A is defined by σπ(A) = {z ∈ σ(A) : |z| = maxw∈σ(A) |w|}, where σ(A) denotes the spectrum of A. Assume that Φ : A → B is a map and the range of Φ contains all operators with rank at most two. It is pr...
