The polarized lepton pair forward-backward asymmetries in B ->rho l(+)l(-) decay using a general, model independent form of the four-Fermi interaction is studied. The general expressions for nine double-lepton polarization forward-backward asymmetries are calculated. The study of the forward-backward asymmetries of the doubly polarized lepton pair proves to be a very useful tool in looking for new physics beyond the standard model.

Double-lepton polarizations in B -> l(+)l(-)gamma decay Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2005-02-01) Double-lepton polarization asymmetries in the B-->l(+)l(-)gamma decay are calculated using the most general, model independent form of the effective Hamiltonian including all possible forms of the interaction. The dependencies of the asymmetries on new Wilson coefficients are investigated. The detectability of the averaged double-lepton polarization asymmetries at LHC is also discussed.
Double-lepton polarization asymmetries in the exclusive B ->rho l+l(-) decay beyond the standard model Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2005-08-01) The double-lepton polarization asymmetries in B ->rho l(+)l(-) decay are analyzed in a model independent framework. The general expressions for nine double-polarization asymmetries are calculated. It is shown that the study of the double-lepton polarization asymmetries proves to be a very useful tool in looking for new physics beyond the standard model.
General analysis of polarization phenomena in inclusive and semi-inclusive radiative decays of B mesons Pak, Namık Kemal; Rekalo, MP; Yilmaz, T (IOP Publishing, 2000-07-01) Polarization characteristics of photons produced in inclusive and semi-inclusive radiative decays of B mesons, B --> gamma + X-s, B --> gamma + h + X', are described in a general model-independent framework, using the structure function formalism.
Sigma(Q)Lambda(Q)pi coupling constant in light cone QCD sum rules Azizi, K.; Bayar, M.; Özpineci, Altuğ (American Physical Society (APS), 2009-03-01) The strong coupling constants g(Sigma Q)Lambda(Q)pi (Q=b and c) are studied in the framework of the light cone QCD sum rules using the most general form of the baryonic currents. The predicted coupling constants are used to estimate the decay widths for the Sigma(Q)->Lambda(Q)pi decays which are compared with the predictions of the other approaches and existing experimental data.
Exclusive gamma gamma -> mu(+)mu(-) production in proton-proton collisions at root s=7TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2012-01-01) A measurement of the exclusive two-photon production of muon pairs in proton-proton collisions at root s = 7 TeV, pp -> p mu(+)mu(-) p, is reported using data corresponding to an integrated luminosity of 40 pb-1. For muon pairs with invariant mass greater than 11.5 GeV, transverse momentum p(T)(mu) > 4 GeV and pseudorapidity 1770.1) p mu(+)mu(-) p) - 3.38(-0.55)(+0.58) (stat.)+/- 0.16 (syst.) +/- 0.14 (lumi.) pb, consistent with the theoretical prediction evaluated with the event generator LPAIR. The ratio...
