Differential observables for the Higgs-strahlung process to all orders in EFT
Sourav Bera, Debsubhra Chakraborty, Susobhan Chattopadhyay +1
We develop methods to obtain the fully differential cross-section for the process to any desired order in effective field theory (EFT). To achieve th…

Towards the HEFT-hedron: the complete set of positivity constraints at NLO
Debsubhra Chakraborty, Susobhan Chattopadhyay, Rick S. Gupta
We present the complete set of positivity bounds on the Higgs Effective Field Theory (HEFT) at next-to-leading order (NLO). We identify the 15 operators that can be constrained by…

Cosmological selection of a small weak scale from large vacuum energy: a minimal approach
Susobhan Chattopadhyay, Dibya S. Chattopadhyay, Rick S. Gupta
We present a minimal cosmological solution to the hierarchy problem. Our model consists of a light pseudoscalar and an extra Higgs doublet in addition to the field content of the S…
