چکیده
s p 1⁄4 7 and 8 TeV. No significant excess is found, and upper limits are set on the production rate of the claimed Xð5568Þ state within the LHCb acceptance. Upper limits are also set as a function of the mass and width of a possible exotic meson decaying to the Bsπ final state. The same limits also apply to a possible exotic meson decaying through the chain B 0 s π , B 0 s → Bsγ where the photon is excluded from the reconstructed decays.

Radiative decays of the (0, 1) strange-bottom mesons
In this article, we assume that the (0, 1) strange-bottom mesons are the conventional bs̄ mesons, and calculate the electromagnetic coupling constants d, g1, g2 and g3 using the light-cone QCD sum rules. Then we study the radiative decays Bs0 → B sγ, Bs1 → Bsγ, Bs1 → B sγ and Bs1 → Bs0γ, and observe that the widths are rather narrow. We can search for the (0, 1) strange-bottom mesons in the inva...

In this article, we take the point of view that the strange-bottomed (0+, 1+) mesons Bs0 and Bs1 are the conventional bs̄ mesons, and calculate the electromagnetic coupling constants d, g1, g2 and g3 with the light-cone QCD sum rules. Then we study the radiative decays Bs0 → B sγ, Bs1 → Bsγ, Bs1 → B sγ and Bs1 → Bs0γ, and observe the decay widths are rather narrow. We can search the strange-bott...
متن کاملA New RSTB Invariant Image Template Matching Based on Log-Spectrum and Modified ICA
Template matching is a widely used technique in many of image processing and machine vision applications. In this paper we propose a new as well as a fast and reliable template matching algorithm which is invariant to Rotation, Scale, Translation and Brightness (RSTB) changes. For this purpose, we adopt the idea of ring projection transform (RPT) of image. In the proposed algorithm, two novel s...

متن کاملA new method for drawing the capacity spectrum for seismic analysis and structural rehabilitation
A review of previous studies shows that there are two general views on how to determine demand in structures through incremental nonlinear static analysis. In the first view, multi-modal methods are used to determine demand in structures. In this view, the applied load pattern is applied to the structure according to the shape of each vibration mode, assuming that the structure deformation foll...
