A Lesson from RττK(*)$R_{\tau \tau }^{K^{(\ast )}}$ and RννK(*)$R_{\nu \nu }^{K^{(\ast )}}$ at Belle II

Fortschritte der Physik, Volume 72, Issue 1, January 2024.
Abstract Within the assumption of Left‐Handed (LH) New Physics (NP), the relations between B(B→K(*)τ+τ−)$\mathcal {B}(B\rightarrow K^{(\ast )} \tau ^+\tau ^-)$ and B(B→K(*)νν¯)$\mathcal {B}(B\rightarrow K^{(\ast )} \nu \bar{\nu })$ for several Beyond the Standard Model (BSM) scenarios are reviewed, commonly considered to explain the Lepton flavor ...

Top Quark Flavor Changing Couplings at a Muon Collider

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.

Constraints on anomalous quartic gauge couplings via $W\gamma jj$ production at the LHC

, 2020
The vector boson scattering at the Large Hadron Collider (LHC) is sensitive to anomalous quartic gauge couplings (aQGCs). In this paper, we investigate the aQGC contribution to $ W \gamma jj$ production at the LHC with $\sqrt{s}=13$ TeV in the context of

Incorporating doubly resonant $W^\pm$ data in a global fit of SMEFT parameters to lift flat directions [PDF]

, 2016
We calculate the double pole contribution to two to four fermion scattering through $W^{\pm}$ currents at tree level in the Standard Model Effective Field Theory (SMEFT).

Missing energy plus jet in the SMEFT [PDF]

Journal of High Energy Physics
We study the production of dineutrinos in proton-proton collisions, with large missing transverse energy and an energetic jet as the experimental signature.

Field reparametrization in SMEFT [PDF]

The European Physical Journal Plus, 2017
Debate topic for effective field theory (EFT) is the choice of a “basis” for ${\rm dim}= 6$ operators. Clearly all bases are equivalent as long as they are a “basis”, containing a minimal set of operators ...

More accurate σ GG → h , Γ h → GG AA Ψ ¯ Ψ $$ \sigma \left(\mathcal{GG}\to h\right),\Gamma \left(h\to \mathcal{GG},\mathcal{AA},\overline{\Psi}\Psi \right) $$ and Higgs width results via the geoSMEFT

Journal of High Energy Physics
We develop Standard Model Effective Field Theory (SMEFT) predictions of σ( GG $$ \mathcal{GG} $$ → h), Γ(h → GG $$ \mathcal{GG} $$ ), Γ(h → AA $$ \mathcal{AA} $$ ) to incorporate full two loop Standard Model results at the amplitude level, in conjunction

Higgs associated production with a vector decaying to two fermions in the geoSMEFT

SciPost Physics
We present the inclusive calculations of a Higgs boson produced in association with massive vector bosons in the Standard Model Effective Field Theory (SMEFT) to order $1/\Lambda^4$ for the 13 TeV LHC.
