An efficient Wavelet-Based Hamiltonian Formulation of Quantum Field Theories using Flow-Equations
Mrinmoy Basak, Debsubhra Chakraborty, Nilmani Mathur
We propose an effective Hamiltonian formulation of quantum field theories using a Daubechies wavelet basis in position space. Combined with flow-equation methods of the similarity…
Heavy baryons with relativistic quarks
Archana Radhakrishnan, Debsubhra Chakraborty, Nilmani Mathur
We present a lattice QCD study of heavy baryons containing charm and bottom quarks, with particular emphasis on the relativistic treatment of all valence quarks. We use …
Quark-Mass Dependence of Light-Nuclei Masses from Lattice QCD and Trace-Anomaly Contributions to Nuclear Bindings
Debsubhra Chakraborty, Noah Chavez, Xiang Gao +2
We present lattice QCD calculations of the masses of the deuteron, dineutron, Helium-3 and Helium-4 with physical sea quarks and valence quark masses corresponding to pion masses b…
Hamiltonian formulation of the -dimensional theory in a momentum-space Daubechies wavelet basis
Mrinmoy Basak, Debsubhra Chakraborty, Nilmani Mathur +1
We apply the wavelet formalism of quantum field theory to investigate nonperturbative dynamics within the Hamiltonian framework. In particular, we employ Daubechies wavelets in mom…
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…
Precisely determining the ground state mass of Spin-3/2 baryon from Lattice QCD
Navdeep Singh Dhindsa, Debsubhra Chakraborty, Archana Radhakrishnan +2
We present the most precise determination to date of the ground-state masses of the triply charmed baryons with both parities, obtained by continuum extrapolation and fully address…
