Charmonium Spectroscopy in Strong Magnetic Fields by QCD Sum Rules: S-Wave Ground States

Sungtae Cho, Koichi Hattori, Su Houng Lee +2

We investigate quarkonium mass spectra in external constant magnetic fields by using QCD sum rules. We first discuss a general framework of QCD sum rules necessary for properly ext…

Superheavy dark matter and IceCube neutrino signals:bounds on decaying dark matter

Carsten Rott, Kazunori Kohri, Seong Chan Park

Superheavy dark matter may show its presence in high energy neutrino signals detected on earth. From the latest results of IceCube, we could set the strongest lower bound on the li…

Radiative and Seesaw Threshold Corrections to the Symmetric Neutrino Mass Matrix

Shivani Gupta, C. S. Kim, Pankaj Sharma

We systematically analyze the radiative corrections to the symmetric neutrino mass matrix at high energy scale, say the GUT scale, in the charged lepton basis. There are sign…

Renormalization Group Evolution of Neutrino Parameters in Presence of Seesaw Threshold Effects and Majorana Phases

Shivani Gupta, Sin Kyu Kang, C. S. Kim

We examine the renormalization group evolution (RGE) for different mixing scenarios in the presence of seesaw threshold effects from high energy scale (GUT) to the low electroweak…

Prediction of leptonic CP phase from perturbatively modified tribimaximal (or bimaximal) mixing

Sin Kyu Kang, C. S. Kim

We consider the perturbatively modified tribimaximal (or bimaximal) mixing to estimate the (Dirac-type) CP phase in neutrino mixing matrix. The expressions for the CP phase are der…

QCD sum rules for magnetically induced mixing between and

Sungtae Cho, Koichi Hattori, Su Houng Lee +2

We investigate the properties of charmonia in strong magnetic fields by using QCD sum rules. We show how to implement the mixing effects between and on the basis of fie…

Top Yukawa coupling measurement with indefinite CP Higgs in

B. Ananthanarayan, Sumit K. Garg, C. S. Kim +2

We consider the issue of the top quark Yukawa coupling measurement in a model in dependent and general case with the inclusion of CP-violation in the coupling. Arguably the best pr…

Phenomenology of the 3-3-1-1 model

P. V. Dong, D. T. Huong, Farinaldo S. Queiroz +1

We discuss a new SU(3)_C X SU(3)_L X U(1)_X X U(1)_N (3-3-1-1) gauge model that overhauls the theoretical and phenomenological aspects of the known 3-3-1 models. Additionally, we s…

Remarks on the lifetime of sterile neutrinos and the effect on detection of rare meson decays M+ -> M'- lepton+ lepton+

Claudio O. Dib, C. S. Kim

We review the detection of the Delta L=2 semileptonic meson decays of the form M(+) -> M'(-) lepton(+) lepton(-) that we studied in a previous work, mediated by a Majorana neutrino…

CP Violation with Majorana neutrinos in K Meson Decays

Claudio O. Dib, Miguel Campos, C. S. Kim

We study the possibility of having CP asymmetries in the decay Kaon(+/-) -> pion(-/+) lepton(+/-) lepton(+/-) (lepton = muon or electron). This decay violates Lepton Number by two…

Color dipole cross section and inelastic structure function

Yu Seon Jeong, C. S. Kim, Minh Vu Luu +1

Instead of starting from a theoretically motivated form of the color dipole cross section in the dipole picture of deep inelastic scattering, we start with a parametrization of the…

Complex 2D Matrix Model and Its Application to Nc-dependence of Hadron Structures

Kanabu Nawa, Sho Ozaki, Hideko Nagahiro +2

We study the internal structure of resonance states in a complex 2D matrix model. We show that the geometry with "exceptional points" in the complex-parameter space can be useful t…
