The lepton polarization asymmetry in the B -> l(+)l(-) decay, when one of the leptons is polarized, is investigated by using the most general form of the effective Hamiltonian. We find allowed regions for the new scalar Wilson coefficients, assuming that the experimental branching ratio is measured within 10% percent uncertainty. Then using these restrictions to the new coefficients the sensitivity of the lepton polarization asymmetry to them is studied. Moreover, it is observed that there are regions of terms describing the scalar interactions, where lepton polarization asymmetry differs from zero, which can serve as a good test for searching new physics beyond the standard model.

Singularities of spectra of infrared reflection of tertiary compounds of the type T1BX2 Hasanlı, Nızamı; Khomutova, M.D.; Sardarly, R.M.; Tagorov, V.I. (Springer Science and Business Media LLC, 1977-07-01) The frequencies of lattice vibrations are calculated for compounds of the type T1BX2 on the basis of the linear-chain model. The calculated frequencies are compared with experimental values for TlGaS2 and TlGaSe2. The good agreement between the calculated and experimental frequencies serves as proof of the applicability of the linear-chain model to compounds of the T1BX2 type. The proposed method of calculation of frequencies makes it possible to predict the theoretical frequencies of lattice vibrations of ...
Atomic chains and lattice vibration characteristics in A2IIIB3VI compounds with tetrahedral coordination of atoms Hasanlı, Nızamı; Khomutova, M.D. (Springer Science and Business Media LLC, 1977-04-01) On the basis of the presence of atomic chains in A2 IIIB3 VI compounds having zincblende defect structure, a linear-chain model is used to calculate the lattice vibration frequencies. The agreement of the calculated and experimental frequencies is an indication of the applicability of the model and enables one to determine the motion of various atoms during the corresponding vibrations.
Singular potentials and moving boundaries in 3D Yuce, C (Elsevier BV, 2004-02-16) In this Letter, the problem of a spinless particle under the time-dependent harmonic oscillator potential and a singular potential with a moving boundary is studied in the spherical coordinates. Some transformations are used to transform the moving boundary conditions to the fixed boundary conditions. An exact solution is constructed.
Thermodynamic study on the magnetic transition and structural phase transition in [(CH3)(2)NH2][Na0.5Fe0.5(HCOO)(3)] by using the Landau phenomenological model Yurtseven, Hasan Hamit (AIP Publishing, 2020-11-01) In this study, we apply the Landau phenomenological model to describe magnetic transition and structural phase transition in a metal formate framework (MOF) of the ferromagnetic [(CH3)(2)NH2][Na0:5Fe0:5(HCOO)(3)], namely, DMNaFe. By using the observed data from the literature for the magnetization, the excess heat capacity (Delta CP), and the dielectric constant (e), we predict some thermodynamic quantities as a function of temperature close to the magnetic transition (T-M 1/4 8:5K) and structural (T-c 1/4 ...
Effective Mass Schrodinger Equation via Point Canonical Transformation Arda, Altug; Sever, Ramazan (IOP Publishing, 2010-07-01) Exact solutions of the effective radial Schrodinger equation are obtained for some inverse potentials by using the point canonical transformation. The energy eigenvalues and the corresponding wave functions are calculated by using a set of mass distributions.
