We demonstrate that the Dalitz-distributions in energies of both unpolarized leptons, produced in the decays B --> K + l(+) + l(-) for l= e, mu, tau, can be a sensitive test for possible new physics beyond the Standard Model. We find measurable characteristics (including the polarization of leptons as well) which are independent of all dirty non-perturbative physics needed in calculating the hadronic form factors. Such characteristics can be used to estimate the presence of possible non-standard mechanisms in a model-independent manner.

Two Higgs doublet model and lepton polarization in the B -> K tau(+)tau(-) decay Alıyev, Tahmasıb; Savcı, Mustafa; Özpineci, Altuğ (IOP Publishing, 1998-01-01) The decay width, forward-backward asymmetry and tau lepton longitudinal and transversal polarization for the exclusive B --> K tau(+)tau(-) decay in a two Higgs doubler model are computed. It is shown that the forward-backward asymmetry and longitudinal polarization of the tau lepton are very effective tools for establishing near physics.
Measurement with the ATLAS detector of multi-particle azimuthal correlations in p plus Pb collisions at root s(NN)=5.02 TeV Aad, G.; et. al. (Elsevier BV, 2013-08-09) In order to study further the long-range correlations ("ridge") observed recently in p + Pb collisions at root s(NN) = 5.02 TeV, the second-order azimuthal anisotropy parameter of charged particles, v(2), has been measured with the cumulant method using the ATLAS detector at the LHC. In a data sample corresponding to an integrated luminosity of approximately 1 mu b(-1), the parameter v(2) has been obtained using two- and four-particle cumulants over the pseudorapidity range vertical bar eta vertical bar < 2...
Determination of the g(V sigma gamma) coupling constant through theprocess gamma plus N -> N plus V with circularly polarized photons Rekalo, MP; Tomasi-Gustafsson, E (Elsevier BV, 2003-02-24) We suggest to measure the t-dependence of the two possible T-even asymmetries for the photoproduction of vector mesons, gamma + rho --> rho + V-0, V-0 = rho or omega, in the collision of circularly polarized photons with a polarized proton target. In the framework of a (pi + sigma)-model, these asymmetries are very sensitive to the relative role of pi- and sigma-exchanges, in the near threshold region.
Measurement of the cross section for electroweak production of Z gamma in association with two jets and constraints on anomalous quartic gauge couplings in proton-proton collisions at root s=8 TeV Khachatryan, V.; et. al. (Elsevier BV, 2017-07-01) A measurement is presented of the cross section for the electroweak production of a Z boson and a photon in association with two jets in proton-proton collisions at root s = 8 TeV. The Z bosons are identified through their decays to electron or muon pairs. The measurement is based on data collected with the CMS detector corresponding to an integrated luminosity of 19.7 fb(-1). The electroweak contribution has a significance of 3.0 standard deviations, and the measured fiducial cross section is 1.86(-0.75)(+...
Measurement of the W -> tau nu(tau) cross section in pp collisions at root s=7 TeV with the ATLAS experiment Aad, G.; et. al. (Elsevier BV, 2012-01-05) The cross section for the production of W bosons with subsequent decay W -> tau nu(tau) is measured with the ATLAS detector at the LHC. The analysis is based on a data sample that was recorded in 2010 at a proton-proton center-of-mass energy of root s = 7 TeV and corresponds to an integrated luminosity of 34 pb(-1). The cross section is measured in a region of high detector acceptance and then extrapolated to the full phase space. The product of the total W production cross section and the W -> tau nu(tau) ...
