One Loop Effective Action up to Dimension Eight: integrating out heavy scalars and fermions (15' + 5') / Chakrabortty, Joydeep (speaker) (IIT Kanpur)
I will discuss the computation of effective action after integrating out heavy scalars and fermions respectively up to dimension eight. The result is very universal. [...]

Precision matching of microscopic physics to the Standard Model Effective Field Theory (SMEFT) / Greljo, Admir (Universitaet Bern (CH)) ; Dawson, Sally (Department of Physics, Brookhaven National Laboratory (US)) ; Lohwasser, Kristin (University of Sheffield (GB)) ; Aebischer, Jason (Universität Zürich (CH)) ; Das Bakshi, Supratim (Universidad de Granada (ES)) ; Carmona, Adrían (Universidad de Granada (ES)) ; Chakrabortty, Joydeep (Indian Institute of Technology Kanpur (IN)) ; Cohen, Timothy (University of Oregon (US)) ; Criado, Juan Carlos (Durham University (UK)) ; Fuentes-Martín, Javier (Universidad de Granada (ES)) et al.
This note gives an overview of the tools for the precision matching of ultraviolet theories to the Standard Model effective field theory (SMEFT) at the tree level and one loop. Several semi- and fully automated codes are presented, as well as some supplementary codes for the basis conversion and the subsequent running and matching at low energies. [...]

Effective limits on single scalar extensions in the light of recent LHC data / Anisha (Indian Inst. Tech., Kanpur) ; Das Bakshi, Supratim (Indian Inst. Tech., Kanpur) ; Banerjee, Shankha (CERN) ; Biekötter, Anke (Durham U., IPPP) ; Chakrabortty, Joydeep (Indian Inst. Tech., Kanpur) ; Kumar Patra, Sunando (Bangabasi Coll.) ; Spannowsky, Michael (Durham U., IPPP)
In this paper, we work with 16 different single scalar particle extensions of the Standard Model. We present the sets of dimension-6 effective operators and the associated Wilson coefficients as functions of model parameters after integrating out the heavy scalars up to 1-loop, including the heavy-light mixing, for each such scenario.

SMEFT / Das Bakshi, Supratim (Indian Inst. Tech., Kanpur) ; Chakrabortty, Joydeep (Indian Inst. Tech., Kanpur) ; Patra, Sunando Kumar (Indian Inst. Tech., Kanpur)
In spite of the non-observation of any new resonances after the discovery of the Standard Model (SM)-Higgs like particle, which announces the success of the SM, we have enough reason to believe the existence of theories beyond it (BSM), with the SM as a part. As any such theory will affect the electro-weak and the Higgs sector, and the sensitivity of these precision observables are bound to increase in near future, indirect estimation of allowed room left for BSM using Standard Model Effective Field Theory (SMEFT) is well-motivated.

The FCC at CERN, a proposed 100-km circular facility with several colliders in succession, culminates with a 100 TeV proton-proton collider. It offers a vast new domain of exploration in particle physics, with orders of magnitude advances in terms of Precision, Sensitivity and Energy. [...]
