Very recently, Belle Collaboration reported observation of a narrow state called Omega(2012) with mass 2012.4 +/- 0.7(stat) +/- 0.6(syst) MeV and width 6.4(-2.0)(+2.5)(stat) +/- 1.6(syst) MeV. We calculate the mass and residue of the Omega(2012) state by employing the QCD sum rule method. Comparison of the obtained results with the experimental data allows us to interpret this state as a 1P orbital excitation of the ground state Omega baryon, i.e., with quantum numbers J(P) = 3-\2.

Determination of the quantum numbers of Sigma(b)(6097)(+/-) via their strong decays
Alıyev, Tahmasıb; Sarac, Y.; Sundu, H. (2019-05-08)
Recent experimental progress has led to the detection of many new hadrons. Very recently, the LHCb Collaboration announced the observation of two new Sigma(b)(6097)(+/-) states in the Lambda(0)(b)pi(+/-) invariant mass distribution, which are considered to be the excited states of the ground-state Sigma((*))(b) baryon. Although almost all of the ground-state baryons have been observed, the fact that only a limited number of excited states have been observed makes them intriguing. Understanding the propertie...
Search for baryon number violation in top-quark decays
Chatrchyan, S.; et. al. (Elsevier BV, 2014-04-01)
A search for baryon number violation (BNV) in top-quark decays is performed using pp collisions produced by the LHC at root s = 8 TeV. The top-quark decay considered in this search results in one light lepton (muon or electron), two jets, but no neutrino in the final state. Data used for the analysis were collected by the CMS detector and correspond to an integrated luminosity of 19.5 fb(-1). The event selection is optimized for top quarks produced in pairs, with one undergoing the BNV decay and the other t...
Analysis of the Lambda b -> Lambda l(+)l(-) decay in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (2010-03-01)
Taking into account the Lambda baryon distribution amplitudes and the most general form of the interpolating current of the Lambda(b), the semileptonic Lambda(b) --> Lambda l(+)l(-) transition is investigated in the framework of the light cone QCD sum rules. Sum rules for all 12 form factors responsible for the Lambda(b) --> Lambda l(+)l(-) decay are constructed. The obtained results for the form factors are used to compute the branching fraction. A comparison of the obtained results with the existing predi...
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.
The integrability of Pauli system in Lorentz violating background
Frank, Mariana; Turan, İsmail; Yurdusen, Ismet (Springer Science and Business Media LLC, 2008-01-01)
We systematically analyze the integrability of a Pauli system in Lorentz violating background at the non-relativistic level both in two- and three-dimensions. We consider the non-relativistic limit of the Dirac equation from the QED sector of the so-called Standard Model Extension by keeping only two types of background couplings, the vector at, and the axial vector b(mu). We show that the spin-orbit interaction comes as a higher order correction in the non-relativistic limit of the Dirac equation. Such an ...
