IoT (Internet of Things) is expected to usher in an era of closely connected world through advanced connectivity of devices, systems and services. IoT goes beyond M2M (Machine to Machine) communication and covers a wide variety of protocols, domains and applications. It is estimated that more than 50 billion devices will be connected to the Internet of… (More)

A current algebra sum rule for the inclusive decays B −→ D + X + ℓ + ν by Bjorken et al. is used to obtain constraints on the Isgur-Wise function ξ(ω) for the B −→ Dℓν decays. In Heavy Quark Effective Theory (HQET) the calculation of weak current matrix elements of hadrons which contain heavy quarks is greatly simplified [1]–[6]. In general, six form… (More)

It is suggested that the narrow meson state seen in the the SELEX experiment is a (c¯ ss¯ s) tetraquark state. Characteristics of other possible tetraquarks formed out of c and s quarks and antiquarks are considered. SELEX experiment has reported [1] a puzzling narrow meson state at a mass of 2632.6 ± 1.6 MeV/c 2 which decays preferentially to D + s (c¯ s)… (More)

If the unitary quark-mixing matrix, V , is moduli symmetric then it depends on three real parameters. This means that there is a relation between the four parameters needed to parametrize a general V. It is shown that there exists a very simple relation involving |V 11 | 2 , |V 33 | 2 , ρ and η. This relation is compared with the present experimental data.… (More)

A parametrization of the 3 × 3 Cabibbo-Kobayashi-Maskawa matrix , V , is presented in which the parameters are the eigenvalues and the components of its eigenvectors. In this parametrization, the small departure of the experimentally determined V from being moduli symmetric (i.e. |V ij | = |V ji |) is controlled by the small difference between two of the… (More)

The CKM-matrix V is written as a linear combination of the unit matrix I and a matrix U which causes intergenerational-mixing. It is shown that such a V results from a class of quark-mass matrices. The matrix U has to be hermitian and unitary and therefore can depend at most on 4 real parameters. The available data on the CKM-matrix including CP-violation… (More)

Starting with the S-wave radial equation for an attractive central potential V (r), we give results for the n(principal quantum number) and the µ (reduced mass) dependence of R n0 (0), the S-wave radial waveunction at the origin, for potentials with definite curvature.

In this paper we study three active neutrino oscillations, favored by recent data from SuperK and SNO, using a new parametrization of the lepton mixing matrix V constructed from a linear combination of the unit matrix I, and a hermitian unitary matrix U , that is, V = cos θI + i sin θU. There are only three real parameters in V including the parameter θ. It… (More)

A new approach to the parametrization of the CKM matrix, V , is considered in which V is written as a linear combination of the unit matrix I and a non-diagonal matrix U which causes intergenerational-mixing, that is V = cos θ I + i sin θ U. Such a V depends on 3 real parameters including the parameter θ. It is interesting that a value of θ = π/4 is… (More)
