We investigate heavy quark symmetries for heavy light meson-antimeson systems in a contact-range effective field theory. In the SU(3) light flavor limit, the leading order Lagrangian respecting heavy quark spin symmetry contains four independent counter-terms. Neglecting 1/m (Q) corrections, three of these low energy constants can be determined by theorizing a molecular description of the X(3872) and Z (b) (10610) states. Thus, we can predict new hadronic molecules, in particular the isovector charmonium partners of the Z (b) (10610) and the Z (b) (10650) states. We also discuss hadron molecules composed of a heavy meson and a doubly-heavy baryon, which would be related to the heavy meson-antimeson molecules thanks to the heavy antiquark-diquark symmetry. Finally, we also study the decay, which is not only sensitive to the short distance part of the X(3872) molecular wave function, as the J/psi pi pi and J/psi 3 pi X(3872) decay modes are, but it is also affected by the long-distance structure of the resonance. Furthermore, this decay might provide some information on the interaction between the charm mesons.

Long-distance structure of the X(3872) Guo, F-K.; Hidalgo-Duque, C.; Nieves, J.; Özpineci, Altuğ; Valderrama, M. Pavon (2014-07-26) We investigate heavy quark symmetries for heavy meson hadronic molecules, and explore the consequences of assuming the X(3872) and Z(b) (10610) as an isoscalar D (D) over bar and an isovector B (B) over bar* hadronic molecules, respectively. The symmetry allows to predict new hadronic molecules, in particular we find an isoscalar 1(++) BB* bound state with a mass about 10580 MeV and the isovector charmonium partners of the Z(b) (10610) and the Z(b) (10650) states. Next, we study the X(3872) -> D-0(D) over b...
Study of heavy quarkonia spectra in the quark model Takan, Taylan; Özpineci, Altuğ; Department of Physics (2012) Conventional Heavy Quarkonium systems, Charmonium and Bottomonium, are believed to be composed of a heavy quark and anti-quark pair. These systems are investigated by di erent methods resulting from di erent approaches to Quantum Chromodynamics (QCD), such as Lattice QCD, E ective Theories and Sum Rules. In this thesis we study the spectrum of Charmonium and Bottomonium using a non-relativistic Quark Model. Assuming one gluon exchange for the short distances and a linear confining potential for long distanc...
Exploring extra dimensions through rare processes Şimşek, Kağan; Turan, İsmail; Department of Physics (2019) We study the single top quark production and decay mechanisms at one-loop level occurring via flavor-changing neutral currents in the Minimal Universal Extra Dimensions (MUED) model. We make a complete study of the model in the Feynman gauge. Especially, we focus on extracting the complete list of 3- and 4-point interactions and determining the mixings among the gauge eigenstates to form the so-called mass eigenstates. Once we have the complete model analyzed, it is implemented via the LanHEP package and tr...
Measurement of the Z -> tau tau cross section with the ATLAS detector Aad, G.; et. al. (2011-12-14) The Z -> tau tau cross section is measured with the ATLAS experiment at the LHC in four different final states determined by the decay modes of the tau leptons: muon-hadron, electron-hadron, electron-muon, and muon-muon. The analysis is based on a data sample corresponding to an integrated luminosity of 36 pb(-1), at a proton-proton center-of-mass energy of root s = 7 TeV. Cross sections are measured separately for each final state in fiducial regions of high detector acceptance, as well as in the full phas...
Phenomenology of the Heavy Flavored Spin 3/2 Baryons in Light Cone QCD Alıyev, Tahmasıb; Özpineci, Altuğ (2008-10-02) Motivated by the results of the recent experimental discoveries for charm and bottom baryons, the masses and magnetic moments of the heavy baryons with J(P) = 3/2(+) containing a single heavy quark are Studied within light Cone QCD sum rules method. Our results on the masses of heavy baryons are in good agreement with predictions of other approaches, as well as with the existing experimental data.
