X(3872) still presents many puzzles more than a decade after its discovery. Some of its properties, like the isospin violating decays, can easily be accommodated in a molecular model, whereas its other properties, such as radiative decays can be more naturally explained in the quarkonium picture. The best of these schemes can be combined in a picture of X(3872) where it is dominantly a molecular state with some charmonium components. In this work, we present a model based on heavy quark symmetry which describes X(3872) as a superposition of molecular and charmonium components.


X(3872) and its heavy quark spin symmetry partners in QCD sum rules

X(3872) presents many surprises after its discovery more than ten years ago. Understanding its properties is crucial to understand the spectrum of possible exotic mesons. In this work, X(3872) meson and its heavy quark spin symmetry (HQSS) partners (including the mesons in the bottom sector) are studied within the QCD Sum Rules approach using a current motivated by the molecular picture of X(3872). We predict four heavy partners to X(3872) and bottomonium with the masses and J(PC) quantum numbers. Obtained ...
X(3872) in Heavy Quark Limit of QCD: Its Partners and Isospin Structure
Özpineci, Altuğ (2014-06-19)
Although it has been more than ten years since the discovery of the X(3872) meson, its properties still contain puzzles. In this work, the results obtained using a correlation function approach on the degenerate partners of the X(3872) will be presented. The isospin structure is also discussed in the same framework. Finally, the X(3872) → D0D¯ 0π decay is proposed to study the isospin structure of the X(3872) meson.
Pattern formation in time series systems due to viscoelastic behavior: Case studies in uniform distribution, normal distribution, stock market index, and music
Gündüz, Güngör (World Scientific Pub Co Pte Lt, 2018-09-01)
A new methodology was introduced to investigate the pattern formation in time series systems due to their viscoelastic behavior. Four stochastic processes, uniform distribution, normal distribution, Nasdaq-100 stock market index, and a melody were studied within this context. The time series data were converted into vectorial forms in a scattering diagram. The sequential vectors can be split into its in-line (or conservative) and out-of-line (or dissipative) components. Thus, one can define the storage and ...
Consistency problem of the solutions of the space fractional Schrodinger equation
Bayin, Selcuk S. (AIP Publishing, 2013-09-01)
Recently, consistency of the infinite square well solution of the space fractional Schrodinger equation has been the subject of some controversy. Hawkins and Schwarz [J. Math. Phys. 54, 014101 (2013)] objected to the way certain integrals are evaluated to show the consistency of the infinite square well solutions of the space fractional Schrodinger equation [S. S. Bayin, J. Math. Phys. 53, 042105 (2012); 53, 084101 (2012)]. Here, we show for general n that as far as the integral representation of the soluti...

Possible deviations from the tau-mu-e universality are discussed in the framework of the standard model with four families and in that of the E6 model. It is shown that the experimental study of spin asymmetry in the process e+e- --> Z --> tau+tau- will give direct information on the real tau-nonuniversality due to the mixing of the usual and exotic fermions.
