A practical approach to perturbative corrections to few-body observables
Sourav Mondal, Martin Schäfer, Mirko Bagnarol +3
We formulate two methods to facilitate the calculation of perturbative corrections to quantum few-body observables. Both techniques are designed for a numerical realization in comb…
Scale-(in)dependence in quantum 4-body scattering
Sourav Mondal, Rakshanda Goswami, Udit Raha +1
We investigate the multi-channel 4-body scattering system using regularized 2- and 3-body contact interactions. The analysis determines the sensitivity of bound-state energies, sca…
Universal characterization of Efimovian System via Faddeev Techniques
Ghanashyam Meher, Sourav Mondal, Udit Raha
We demonstrate remnant structural universality in a putative S-wave -halo-bound system in the channel by invoking the zero-coupling limit (ZCL), which elim…
CFNS Ad-Hoc meeting on Radiative Corrections Whitepaper
Andrei Afanasev, Jaseer Ahmed, Igor Akushevich +25
Current precision scattering experiments and even more so many experiments planed for the Electron Ion Collider will be limited by systematics. From the theory side, a fundamental…
Investigation of () Hypernucleus in Low-energy Pionless Halo Effective Theory
Ghanashyam Meher, Udit Raha
In the strangeness sector, we study the () three-body system using pionless halo effective field theory (EFT), which provides a systematic mode…
Radiative and chiral corrections to elastic lepton-proton scattering in chiral perturbation theory
Pulak Talukdar, Vanamali C. Shastry, Udit Raha +1
A unified treatment of both chiral and radiative corrections to the low-energy elastic lepton-proton scattering processes is presented in Heavy Baryon Chiral Perturbations Theory.…
