Recently CDF has reported a 4.1 sigma excess in the distribution of the dijet invariant mass between 120-160 GeV in Wjj event sample in 7.3 fb^{-1} of data, which has generated considerable interest. We offer a possible explanation of this…
We measure the top quark mass in top-antitop events using up to 3.6 /fb of proton-antiproton collisions at sqrt{s}=2 TeV. New results are described for matrix element methods with single lepton and dilepton channels, and template methods…
We present a study of the dijet invariant mass distribution for the reaction $\pbp \to 2 $jets$+\gamma+X$, at a center of mass energy of 1.8 TeV, using data collected by the CDF experiment. We compare the data to predictions for the…
Recently, an excess of events in diphoton channel with invariant mass of about 750 GeV has been reported by the ATLAS and CMS Collaborations. Considering it as a tantalizing hint for new physics beyond the Standard Model (SM), we propose a…
The W boson mass (mW) is a key parameter of the standard model, constraining the mass of the unobserved Higgs boson. Using Tevatron ppbar collision data from 1992-1996, the CDF and D0 collaborations measured mW to a precision of 59 MeV. The…
A search is presented for charge-asymmetric production of a W' boson that has been proposed to accommodate the forward-backward asymmetry observed in the production of top-antitop quark pairs at the Tevatron. The new heavy W' boson would be…
We interpret the reported disagreement between the measured ratio, R_{10}, of the W + 1 jet cross-section to the W + 0 jet cross-section at the Tevatron and the Standard Model (SM) prediction, as the effect of interactions mediated by a…
We report on a search for the standard model Higgs boson produced in association with a vector boson in the full data set of proton-antiproton collisions at $\sqrt{s} = 1.96$ TeV recorded by the CDF II detector at the Tevatron,…
We present a search for standard model Higgs boson production in association with a W boson in proton-antiproton collisions ($p\bar{p}\to W^\pm H \to \ell\nu b\bar{b}$) at a center of mass energy of 1.96 TeV. The search employs data…
The LHC collaborations ATLAS and CMS recently reported on the excess of the events in the diphoton final states at the invariant mass of about $750~ \text{GeV}$. In this article we speculate on the possibility that the excess arises from…
A recent preliminary investigation based on Durgut's report at the American Physical Society site shows a structure at $18.4~ {\rm GeV}$ exists in the invariant mass distribution of $\Upsilon l^+l^- ~ (l = e,\, \mu)$ at the LHC…
We show the latest results from the CDF and D0 collaborations on the study of the Higgs boson, stemming from the analysis of the entire Tevatron Run\,II dataset. Combining the results of many individual analyses, most of which use the full…
We present results of searches for diphoton resonances produced both inclusively and also in association with a vector boson (W or Z) using 100 pb^{-1} of p\bar p collisions using the CDF detector. We set upper limits on the product of…
We present a new measurement of the top quark mass in $t\bar t$ events in which both $W$ bosons from top quarks decay into lepton ($e \nu,\mu \nu$). We use events collected by the CDF experiment from $p\bar p$ collisions at \sqrt s=1.8 TeV…
The recently reported CDF excess at $120\,-\, 160\,GeV$ in invariant mass distribution of jet pairs accompanying $W$-boson is tentatively interpreted as a bound state of two $W$ decaying to quark-anti-quark pair. Non-perturbative effects of…
Latest results are presented in the search for low mass standard model Higgs production in association with a $W$ boson, based on large luminosity data samples collected at the CDF and D0 Experiments at the Fermilab Tevatron $p\bar{p}$…
Motivated by the bulk mixing $\xi R_5 H^{\dagger}H$ between a massive radion and a bulk scalar Higgs in warped extra dimensions, we construct an effective four dimensional action that---via the AdS/CFT correspondence---describes the most…
The CDF collaboration reported an excess in the production of two jets in association with a $W$. We discuss constraints on possible new particle state interpretations of this excess. The fact of no statistically significant deviation from…
A new report for the measurement of the W boson mass has been provided by the CDF II experiment. The measured value of the W boson mass is given to be $m_W^{\text{CDF II}} = 80.4335 \pm 0.0094$ GeV which shows $7\sigma$ deviation from the…
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 simple extension of the Standard Model (SM)…
