Triplet Dark Matter from leptogenesis

Jae Ho Heo, C. S. Kim

A triplet dark matter candidate from thermal leptogenesis is considered with building a model. The model is based on the standard two Higgs doublet model and seesaw mechanism with…

CP violations in $π^{\pm}$ Meson Decay

Gorazd Cvetič, C. S. Kim, Jilberto Zamora-Saá

We study the pion decays with intermediate on-shell neutrinos $N$ into two electrons and a muon, $π^{\pm} \to e^{\pm} N \to e^{\pm} e^{\pm} μ^{\mp} ν$ . We investigate the branching…

QCD effective potential with strong U(1)_{em} magnetic fields

Sho Ozaki

We derive the analytic expression for the one-loop $S U (N_{c})$ QCD effective potential including $N_{f}$ flavor quarks which non-linearly interact with the chromo-magnetic backgrou…

Magnetic Moments of Bottom Baryons: Effective mass and Screened Charge

Rohit Dhir, C. S. Kim, R. C. Verma

We calculate the magnetic moments of low lying heavy flavor bottom baryons using effective quark mass and shielded quark charge scheme. We obtain the magnetic moments of both $J^P…

Corrections for tribimaximal, bimaximal and democratic neutrino mixing matrices

Sumit K. Garg, Shivani Gupta

In this work we analyze the corrections to tribimaximal (TBM), bimaximal (BM) and democratic (DC) mixing matrices for explaining large reactor mixing angle $θ_{13}$ and checking th…

First Estimates of Nonleptonic $B_{c} \to A T$ Weak Decays

Rohit Dhir, C. S. Kim

We obtain the first estimates of branching ratios for the weak decays of $B_{c}$ meson decaying to two orbitally excited mesons namely, axial-vector meson ( $A$ ) and tensor meson ( $T$ …

QCD Sum Rule Study for a Possible Charmed Pentaquark Θc(3250)

R. M. Albuquerque, S. H. Lee, M. Nielsen

We use QCD sum rules to study the possible existence of a Θc(3250) charmed pentaquark. We consider the contributions of condensates up to dimension-10 and work at leading order in…

Neutral-pion reactions induced by chiral anomaly in strong magnetic fields

Koichi Hattori, Kazunori Itakura, Sho Ozaki

We investigate decay and production of neutral pions in strong magnetic fields. In the presence of strong magnetic fields, transition between a neutral pion and a virtual photon be…

$B \to D K_{0, 2}^{*}$ Decays: PQCD analysis to determine CP violation phase angle $γ$

C. S. Kim, Run-Hui Li, Wei Wang

$B^{\pm} \to (D^{0}, D ˉ^{0}, D_{C P}) K_{0, 2}^{*\pm}$ decays are helpful in determining the CP violation angle $γ$ , and we analyze these decay processes within the perturbative QCD app…

Probing the indefinite CP nature of the Higgs Boson through decay distributions in the process $e^{+} e^{-} \to t t ˉ Φ$

B. Ananthanarayan, Sumit K. Garg, Jayita Lahiri +1

The recently discovered scalar resonance at the LHC is now almost confirmed to be a Higgs Boson, whose CP properties are yet to be established. At the ILC with and without polarize…

Spontaneous CP Violation in $A_{4}$ Flavor Symmetry and Leptogenesis

Y. H. Ahn, Sin Kyu Kang, C. S. Kim

We propose a simple renormalizable model for the spontaneous CP violation based on $S U (2)_{L} \times U (1)_{Y} \times A_{4}$ symmetry in a radiative seesaw mechanism, which can be gua…

Implication of a vanishing element in 3+1 Scenario

Monojit Ghosh, Srubabati Goswami, Shivani Gupta +1

In this paper we study the phenomenological implications of the one zero textures of low energy neutrino mass matrices in presence of a sterile neutrino. We consider the 3+1 scheme…

Charge Asymmetry of Weak Boson Production at the LHC and the Charm Content of the Proton

Francis Halzen, Yu Seon Jeong, C. S. Kim

We investigate the production of the weak bosons $W^{+}$ , $W^{-}$ and $Z$ at the LHC as a function of their rapidity, reconstructed {\it experimentally} from their leptonic decay. We s…

How good is μ-τsymmetry after results on non-zero θ_{13}?

Shivani Gupta, Anjan S. Joshipura, Ketan M. Patel

Viability of the μ-τinterchange symmetry imposed as an approximate symmetry (1) on the neutrino mass matrix {\cal M}_{νf} in the flavour basis (2) simultaneously on the charged lep…
