The flux tube model of hybrid mesons is studied in the context of the relativistic equation in the adiabatic approximation. The moment of inertia of the rigid-rod flux tube is considered in the kinetic part of the interaction. The nonrelativistic and relativistic one scalar bead flux tube is integrated numerically and compared with the adiabatic flux tube small oscillation approximation. The relativistic scalar bead picture suggests that the lowest gluonic excitation of a massive gluon is color octet q (q) over bar pair while the conventional mesons are color singlet as usual. We estimate the lowest hybrid charmonium states as 1(1)P = 4.17 +/- 0.03 and 1(1)D = 4.39+/-0.05 GeV with color octet q (q) over bar pair and as 1(1)P = 3.78+/-0.05 and 1(1)D = 4.04 +/- 0.09 GeV with color singlet q (q) over bar pair. These results are also confirmed by the adiabatic flux tube small oscillation approximation when the hybrid energy gap is adjusted phenomenologically to M-Hc = M-ground + 1GeV.

Angular analysis of the decay B+ -> K+mu(+)mu(-) in proton-proton collisions at root s=8 TeV
Sirunyan, A. M.; et. al. (American Physical Society (APS), 2018-12-01)
The angular distribution of the flavor-changing neutral current decay B+ -> K+mu(+)mu(-) is studied in proton-proton collisions at a center-of-mass energy of 8 TeV. The analysis is based on data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 20.5 fb(-1). The forward-backward asymmetry A(FB) of the dimuon system and the contribution F-H from the pseudoscalar, scalar, and tensor amplitudes to the decay width are measured as a function of the dimuon mass squared. The m...
Neutrino oscillations induced by spacetime torsion
Adak, M; Dereli, T; Ryder, LH (IOP Publishing, 2001-04-21)
The gravitational neutrino oscillation problem is studied by considering the Dirac Hamiltonian in a Riemann-Cartan spacetime and calculating the dynamical phase. Torsion contributions which depend on the spin direction of the mass eigenstates are found. These effects are of the order of Planck scales.
Gravitational interactions in 2+1 dimensions
Dereli, Tekin; Tucker, Robin W. (IOP Publishing, 1988-7-1)
Modifications to Einstein's vacuum equations for gravitation in 2+1 dimensions are studied. The addition of the Schouten-Eisenhart 2-forms to the field equations admits gravitational wave solutions although no non-trivial static rotationally symmetric metrics exist. Higher-order derivative models for the metric are discussed together with a 2+1 Brans-Dicke theory. The latter is solved for a static metric exhibiting singularities.
Electric dipole moments of charged leptons and lepton flavor violating interactions in the general two Higgs doublet model
Iltan, EO (American Physical Society (APS), 2001-07-01)
We calculate the electric dipole moment of the electron using the experimental result of the muon electric dipole moment and upper limit of the BR(mu-->e gamma) in the framework of the general two Higgs doubler model. Our prediction is 10(-32) e cm, which lies in the experimental current limits. Further, we obtain constraints for the Yukawa couplings )over bar>(D)(N,taue) and )over bar>(D)(N,tau mu). Finally, we present an expression which connects the BR(tau-->mu gamma) and the electric dipole moment of th...
Magnetic moment of the rho meson in QCD light cone sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2003-09-01)
The magnetic moment mu of the rho meson is studied in QCD light cone sum rules, and it is found that mu=(2.3+/-0.5), in units of e/2m(rho). A comparison of our result on the magnetic moment of the rho meson with the predictions of the other approaches is presented.
