Renormalization of the SMEFT to Dimension Eight: Fermionic Interactions II
Supratim Das Bakshi, Mikael Chala, Zhe Ren
We compute the one-loop mixing of bosonic and two-fermion interactions into two-fermion operators in the dimension-eight Standard Model Effective Field Theory (SMEFT). Together wit…
Relevance of one-loop SMEFT matching in the 2HDM
Supratim Das Bakshi, Sally Dawson, Duarte Fontes +1
The Two-Higgs Doublet Model (2HDM) is a well understood alternative to the Standard Model of particle physics. If the new particles included in the 2HDM are at an energy scale much…
Running beyond ALPs: shift-breaking and CP-violating effects
Supratim Das Bakshi, Jonathan Machado-Rodríguez, Maria Ramos
We compute the renormalization group equations (RGEs) of the Standard Model effective field theory (EFT) extended with a real scalar singlet, up to dimension-five and one-loop accu…
Computing Tools for Effective Field Theories
Jason Aebischer, Matteo Fael, Javier Fuentes-Martín +30
In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In…
Higgs Footprints of Hefty ALPs
Anisha, Supratim Das Bakshi, Christoph Englert +1
We discuss axion-like particles (ALPs) within the framework of Higgs Effective Field Theory, targeting instances of close alignment of ALP physics with a custodial singlet characte…
Renormalisation of SMEFT bosonic interactions up to dimension eight by LNV operators
Supratim Das Bakshi, Álvaro Díaz-Carmona
We present the renormalisation group running of the bosonic operators of the Standard Model effective field theory by the Lepton Number Violating operators (LNVs) at 1-loop order u…
Theory Techniques for Precision Physics -- Snowmass 2021 TF06 Topical Group Report
Radja Boughezal, Zoltan Ligeti, Wolfgang Altmannshofer +26
The wealth of experimental data collected at laboratory experiments suggests that there is some scale separation between the Standard Model (SM) and phenomena beyond the SM (BSM).…
Towards the renormalisation of the Standard Model effective field theory to dimension eight: Bosonic interactions II
Supratim Das Bakshi, Mikael Chala, Álvaro Díaz-Carmona +1
We calculate the renormalisation group running of the bosonic Standard Model (SM) effective operators at one loop and to order , with GeV being the electroweak…
Effective limits on single scalar extensions in the light of recent LHC data
Anisha, Supratim Das Bakshi, Shankha Banerjee +4
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 c…
Landscaping CP-violating BSM scenarios
Supratim Das Bakshi, Joydeep Chakrabortty, Christoph Englert +2
We consider a wide range of UV scenarios with the aim of informing searches for CP violation at the TeV scale using effective field theory techniques. We demonstrate that broad the…
Classifying Standard Model Extensions Effectively with Precision Observables
Supratim Das Bakshi, Joydeep Chakrabortty, Michael Spannowsky
Effective theories are well established theoretical frameworks to describe the effect of energetically widely separated UV models on observables at lower energy scales. Due to the…
Hilbert Series and Plethystics: Paving the path towards 2HDM- and MLRSM-EFT
Anisha, Supratim Das Bakshi, Joydeep Chakrabortty +1
Effective Field Theory technique is one of the most elegant ways to capture the impact of high scale theory, if any, at some low energy by incorporating higher mass dimensional ($\…
