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(…
Polyakov Loops Tame Phase Transitions
Lisa Biermann, Joydeep Chakrabortty, Christoph Englert
We estimate the impact of Polyakov loop (PL) contributions on electroweak phase transitions (PTs). We show that the PL, which is unavoidable in thermal gauge field theory, tends to…
Higher-dimensional operators and Polyakov loop in hot Scalar QED from the heat kernel
Siddhartha Bandyopadhyay, Joydeep Chakrabortty, Debmalya Dey +2
Using the finite-temperature heat kernel method, we compute the gauge-invariant effective Lagrangian up to dimension-six for massive hot scalar QED. We propose two complementary me…
Electroweak Scalar Effects Beyond Dimension-6 in SMEFT
Nilabhra Adhikary, Tisa Biswas, Joydeep Chakrabortty +2
The Standard Model Effective Field Theory (SMEFT) provides a robust framework for probing deviations in the couplings of Standard Model particles from their theoretical predictions…
One-loop Effective Action up to any Mass-dimension for Non-degenerate Scalars and Fermions including Light-Heavy Mixing
Upalaparna Banerjee, Joydeep Chakrabortty, Shakeel Ur Rahaman +1
We propose a Heat-Kernel-based method to compute one-loop effective action up to any mass-dimension with arbitrary numbers of non-degenerate scalars and fermions. We demonstrate ou…
One-loop Effective Action up to Dimension Eight: Integrating out Heavy Fermion(s)
Joydeep Chakrabortty, Shakeel Ur Rahaman, Kaanapuli Ramkumar
We present the universal one-loop effective action up to dimension eight after integrating out heavy fermion(s) using the Heat-Kernel method. We have discussed how the Dirac operat…
