The recent CDF W mass measurement of 80,433 ± 9 MeV is the most precise direct measurement. However, this result deviates from the Standard Model predicted mass of 80,359.1 ± 5.2 MeV by 7 σ . The CDF experiment used an older version of the ResBos code that was only accurate at NNLL+NLO, while the state-of-the-art ResBos2 code is able to make predictions at N 3 LL+NNLO accuracy. We determine that the data-driven techniques used by CDF capture most of the higher order corrections, and using… 

Leptoquark-vectorlike quark model for m W (CDF), ( g − 2) µ , R K ( ∗ ) anomalies and neutrino mass

Very recently, a substantial 7 σ deviation of the W -boson mass from the Standard Model (SM) prediction has been reported by the CDF collaboration. Furthermore, the Muon g-2 Experiment recently

Tripling down on the W boson mass

A new precision measurement of the W boson mass has been announced by the CDF collaboration, which strongly deviates from the Standard Model prediction. In this article, we study the implications of

The Radiative Flavor Template at the LHC: Lepton non-universality and g-2

The Standard Model of Particle Physics and its description of Nature have been recently chal-lenged by a series of precision measurements performed via different accelerator machines. Sta-tistically

Understanding PDF uncertainty on the $W$ boson mass measurements

We study the dependence of the transverse mass distribution of the charged lepton and the missing energies on the parton distributions (PDFs) adapted to the $W$ boson mass measurements at the CDF

Leptoquark-vectorlike quark model for the CDF $m_W$, $(g-2)_\mu$, $R_{K^{(\ast)}}$ anomalies and neutrino mass

Very recently, a substantial 7 σ deviation of the W -boson mass from the Standard Model (SM) prediction has been reported by the CDF collaboration. Furthermore, the Muon g-2 Experiment recently

W-mass anomaly in the simplest linear seesaw mechanism

$W$ boson mass shift, dark matter and $(g-2)_\ell$ in ScotoZee model

We present a singly charged scalar extension of the Scotogenic model, ScotoZee, which resolves the recently reported deviations in W boson mass as well as lepton g − 2. The model admits a scalar or a

First Run II Measurement of the W Boson Mass with CDF

The CDF collaboration has analyzed ~200/pb of Tevatron Run II data taken between February 2002 and September 2003 to measure the W boson mass. With a sample of 63964 W->e nu decays and 51128 W->mu nu

On the implications of positive W mass shift

We investigate the phenomenological implications of the recent W mass measurement by the CDF collaboration, which exhibits tension with the standard model (SM) electroweak fit. Performing the fit to

Parton distributions from high-precision collider data

We present a new set of parton distributions, NNPDF3.1, which updates NNPDF3.0, the first global set of PDFs determined using a methodology validated by a closure test. The update is motivated by

The new ABMP16 PDF

We present an update of the ABM12 PDF analysis including improved constraints due to the final version of the inclusive DIS HERA data, the Tevatron and LHC data on the $W$- and $Z$-production and

Status of the two-Higgs-doublet model in light of the CDF $m_W$ measurement

The most recent the W -boson mass measurement by the CDF Collaboration with a substantially reduced uncertainty indicated a large deviation from the standard model prediction, as large as 7 σ if

Electroweak dark matter model accounting for the CDF W -mass anomaly

Recently, the CDF collaboration reported a new measurement of the W boson mass M W = 80 . 4335 ± 0 . 0094 GeV, which shows a ∼ 7 σ deviation from the standard model prediction 80 . 3545 ± 0 . 0057

W-boson mass in the triplet seesaw model

The CDF collaboration has recently published a precision measurement of the W -boson mass that differs from the Standard Model prediction by seven standard deviations. This result can be explained
