X(3872) in Heavy Quark Limit of QCD: Its Partners and Isospin Structure

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.

X(3872) and its charmonium content in Heavy Quark limit
Cincioglu, Elif; Nieves, Juan; Özpineci, Altuğ (EDP Sciences; 2016-06-30)
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 descr...
X(3872) and its heavy quark spin symmetry partners in QCD sum rules
Mutuk, Halil; Sarac, Yasemin; Gumus, Hasan; Özpineci, Altuğ (Springer Science and Business Media LLC, 2018-11-08)
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 ...
Partial direct product difference sets and almost quaternary sequences
Özden, Büşra; Yayla, Oğuz (2021-01-01)
In this paper, we study the m-ary sequences with (non-consecutive) two zero-symbols and at most two distinct autocorrelation coefficients, which are known as almost m-ary nearly perfect sequences. We show that these sequences are equivalent to P-partial direct product difference sets (PDPDS), then we extend known results on the sequences with two consecutive zero symbols to non-consecutive case. Next, we study the notion of multipliers and orbit combination for P-PDPDS. Finally, we present two construction ...
Rare radiative B-s -> tau(+) tau(-) gamma decay in the two Higgs doublet model
Iltan, EO; Turan, Gürsevil (2000-02-01)
The radiative B-s-->tau(+)tau(-)gamma decay is investigated in the framework of the two Higgs doublet model. The dependence of the differential branching ratio on the photon energy and the branching ratio on the two Higgs doublet model parameters m(H+) and tan beta are studied. It is shown that there is an enhancement in the predictions of the two Higgs doublet model compared to the standard model case. We also observe that contributions of neutral Higgs bosons to the decay are sizable when tan beta is large.
Numerical solution of solidification in a square prism using an algebraic grid generation technique
Dursunkaya, Zafer (Springer Science and Business Media LLC, 2003-12-1)
The solidification of an infinitely long square prism was analyzed numerically. A front fixing technique along with an algebraic grid generation scheme was used, where the finite difference form of the energy equation is solved for the temperature distribution in the solid phase and the solid-liquid interface energy balance is integrated for the new position of the moving solidification front. Results are given for the moving solidification boundary with a circular phase change interface. An algebraic grid ...
