In this work we focus on the analysis of the X(3872) -> D-0(D) over bar (0)pi(0) decay assuming a molecular picture for the X(3872) state within an effective field theory (EFT) approach. This decay is sensitive to the long-distance structure of the X(3872); in sharp contrast with the main decay channels: J/psi pi pi and J/psi 3 pi. We show that the final state interactions in the D (D) over bar system can be important and that the measurement of this partial decay width can provide a constrain on the low energy constants (LECs) of the D(*)(D) over bar(*) EFT.

Measurement of the production cross section of prompt j/psi mesons in association with a W (+/-) boson in pp collisions root s=7 TeV with the ATLAS detector
Aad, G.; et. al. (Springer Science and Business Media LLC, 2014-04-01)
The process pp -> W (+/-) J/psi provides a powerful probe of the production mechanism of charmonium in hadronic collisions, and is also sensitive to multiple parton interactions in the colliding protons. Using the 2011 ATLAS dataset of 4.5 fb(-1) of root s= 7 TeV pp collisions at the LHC, the first observation is made of the production of W (+/-) + prompt J/psi events in hadronic collisions, using W (+/-) -> mu nu(mu) and J/psi -> mu(+)mu(-) center dot A yield of W (+/-) + prompt J/psi events is observed, w...
Probing the phases in the MSSM via e(+)e(-) -> hA
Demir, DA (Elsevier BV, 1999-10-21)
In the presence of the supersymmetric CP phases, e(+)e(-) --> Z* --> hA scattering is analyzed, with special emphasis on Z* hA vertex, taking into account radiatve corrections due to dominant top quark and top squark loops in the Higgs sector as well as the vertex formfactors. It is found that the lightest Higgs remains essentially CP-even whereas the heavier ones mix with each other strongly. Moreover, the supersymmetric CP phases are found to create tree-level couplings between a pseudoscalar and identica...
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...
Searches for W ' bosons decaying to a top quark and a bottom quark in proton-proton collisions at 13TeV
Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2017-08-01)
Searches are presented for heavy gauge bosons decaying into a top and a bottom quark in data collected by the CMS experiment at root s = 13TeV that correspond to an integrated luminosity of 2.2 and 2.6 fb 1 in the leptonic and hadronic analyses, respectively. Two final states are analyzed, one containing a single electron, or muon, and missing transverse momentum, and the other containing multiple jets and no electrons or muons. No evidence is found for a right-handed W' boson (W'(R)) and the combined analy...
Unparticle effects in rare t -> cgg decay
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2008-09-01)
In this work the flavor-changing, rare t -> cgg decay induced by mediation of scalar and tensor unparticles is studied. Using the standard model result for the branching ratio of the t -> cgg decay, the parameter space of d(U) and Lambda(U), where the branching ratio of this decay exceeds the one predicted by the standard model, is obtained. Measurement of the branching ratio larger than 10(-9) can give valuable information for establishing unparticle physics.
