Due to the lack of direct evidence in the search for new physics (NP), the Effective Field Theory (EFT) framework offers an indirect and model-independent approach to parameterize NP effects. In this talk, I will focus on the non-linear EFT framework, also known as Higgs Effective Field Theory (HEFT), and include next-to-leading order (NLO) bosonic operators to study Higgs-related processes at...
The Standard Model Effective Field Theory (SMEFT) is an essential tool for probing physics beyond the Standard Model. With New Physics signals remaining elusive, deriving constraints on SMEFT Wilson coefficients is increasingly important in order to pinpoint its low-energy effects. This talk presents comprehensive global fits of SMEFT under the Minimal Flavour Violation (MFV) hypothesis. We...
We have, for the first time, computed a model-independent two-loop dimension-six effective action by integrating out heavy scalars. As an example, we applied this to the electroweak complex triplet scalar and the 2HDM model. In this talk, I will discuss our approach to computing the two-loop effective action using the Heat-Kernel method, which simplifies the process by avoiding extensive...
Scalar Diquarks which only couple to right-handed down-type quarks are difficult to resolve at colliders due to being able to hide amongst jet backgrounds. Using Standard Model Effective Field Theory we can also find indirect constraints on these diquarks from observables in flavour physics such as neutral meson oscillations and meson decays. Comparing current measurements from colliders and...
We study CP violation within the Standard Model Effective Field Theory framework, focusing on the impact of CP-odd dimension-6 operators entering gluon-induced double Higgs and double Z and W production. After extending the SMEFTatNLO model to include the relevant operators, we study differential distributions for these processes and compare their features to those obtained from CP-conserving...
Charged lepton flavor violation (cLFV) processes, potentially important for various beyond the Standard Model physics scenarios are analyzed in the Standard Model effective field theory framework. We consider the most relevant two-quark–two-lepton (2q2ℓ) operators for the leptonic and semileptonic LFV B-decay (LFVBD) processes Bs→μ+e-,B+→K+μ+e-,B0→K*0μ+e-, and Bs→ϕμ-e+. We analyze the...
We consider the renormalization group equations within the Standard Model Effective Field Theory and compute two-loop contributions proportional to the top quark Yukawa coupling for the operator generating an effective Higgs-gluon coupling, focusing on the Yukawa-like operator. These two-loop running effects are relevant for processes where the effective Higgs-gluon coupling contributes at a...
