Soft Collinear Effective Theory for Heavy QCD Axions
Deepanshu Bisht, Sabyasachi Chakraborty, Siddhartha Karmakar +1
We develop a soft-collinear effective theory (SCET) framework for heavy QCD axion, considering two low-energy realizations and taking as a benchmark mode. In the first re…

Hilbert Series of Pseudoscalar Mesons: Operators and Sum Rules
Joydeep Chakrabortty, Sabyasachi Chakraborty, Siddhartha Karmakar
We construct the complete non-redundant basis of operators built from pseudoscalar mesons using the Hilbert series method, subject to the global flavor symmetry $SU(3)_L \times SU(…

Finite-temperature operator basis on for SMEFT
Joydeep Chakrabortty, Bruno Siqueira Eduardo, Siddhartha Karmakar +1
We present the first complete non-redundant operator basis for the Standard Model Effective Field Theory (SMEFT) at finite temperature, using the imaginary-time formalism. By emplo…
