Motivated by CDF recent measurements on di-jet invariant mass spectrum where di-jet is associated production with charged leptons ($e/\mu$) and missing energy, we re-examine the previous proposed massive color-octet axial-vector-like boson $Z_c$. Our simulation showed that the di-jet bump around 120-160 GeV can be induced by $Z_c$ with effective coupling $g_{Z_c q \bar q} =0.2 g_s$ (q represents the quark other than top and $g_s$ is the strong coupling constant). Moreover our numerical…

Implications of effective axial-vector coupling of gluon fortt¯spin polarizations at the LHC
We analyze the impact of effective axial-vector coupling of the gluon on spin polarization observables in $t\bar{t}$ pair production at the LHC. Working at leading order in QCD, we compute the
Measurement of the charge asymmetry in top quark pair production in $pp$ collision data at $\sqrt{s} = 7\,$TeV using the ATLAS detector
A measurement of the charge asymmetry in the production of top quark pairs in the semileptonic decay channel has been performed. A dataset corresponding to an integrated luminosity of $1.04\,{\rm
Colored scalars and the CDF W+dijet excess
A bstractThe recent data on W + dijet excess reported by CDF may be interpreted as the associated production of a W and a new particle of mass about 150 GeV which subsequently decays into two hadron
Weak-triplet, color-octet scalars and the CDF dijet excess
We extend the standard model to include a weak-triplet and color-octet scalar. This 'octo-triplet' field consists of three particles, two charged and one neutral, whose masses and renormalizable
Phenomenology of a light gluon resonance in top-physics at Tevatron and LHC
We present a phenomenological analysis of the recent Tevatron results on the $ t\overline t $ forward-backward asymmetry and invariant-mass spectrum assuming a new contribution from an s-channel
Anomaly Puzzle, Curved-Spacetime Spinor Hamiltonian, and String Phenomenology
In the first part of this dissertation, we study two different aspects of string phenomenology. First we discuss the complementary signals of low mass superstrings at the proposed electron-positron
Dissecting the Wjj Anomaly: Diagnostic Tests of a Leptophobic Z'
We examine the scenario where a leptophobic Z{prime} boson accounts for the excess of events in the Wjj channel as observed by CDF. We assume generation independent couplings for the Z{prime} and
Dimuon CP asymmetry in B decays and collider signals in two Higgs doublet models
A bstractWe analyze the puzzle of the dimuon CP asymmetry in B decays in two Higgs doublet models. We show that the flavor changing neutral current induced by the Higgs coupling in a general two
Measuring the bottom-quark forward-central asymmetry at the LHC
A bstractMeasurements of the top quark forward-backward asymmetry performed at the Tevatron suggest that new-physics may be playing a role in tt production. To better understand the source of the
W plus two jets from a quasi-inert Higgs doublet
We show that, the result recently reported by the CDF collaboration showing an excess in the invariant mass distribution of jet pairs produced in association with a W-boson can be explained by a
