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…
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…
Precise study of triply charmed baryons
Navdeep Singh Dhindsa, Debsubhra Chakraborty, Archana Radhakrishnan +2
We present the most precise results for the ground state mass of the triply-charmed spin- baryon using lattice quantum chromodynamics. The calculations are performed on six $N…
