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…
Axion EFT in the BMHV Scheme: Flavor Currents, Evanescent Operators and Ward Identities
Deepanshu Bisht, Sabyasachi Chakraborty, Atanu Samanta
We present a systematic analysis of axion effective field theory within the Breitenlohner-Maison-`t Hooft-Veltman (BMHV) scheme, focusing on the renormalization of fermionic dimens…
Magnetic field amplification and decay in cosmic string wakes
Deepanshu Bisht, Dilip Kumar, Soumen Nayak +1
We do a detailed study on vortex formation in a magnetized plasma within the spacetime of a moving cosmic string using analytical and numerical methods. The conical spacetime aroun…
A comprehensive study of ALPs from -decays
Deepanshu Bisht, Sabyasachi Chakraborty, Atanu Samanta
We present a comprehensive study of axion-like particles (ALPs) through flavor changing neutral current processes, such as followed by $a\to\text{hadronic}, γγ,μ^+μ^…
