Instanton-induced effects in interquark forces, light-front wave functions and formfactors [PDF]

EPJ Web of Conferences, 2022
Exclusive processes are traditionally described by perturbative hard blocks and “distribution amplitudes" (DAs), matrix elements of operators of various chiral structure and twist. One paper (with I.Zahed) calculate instanton contribution to hard blocks,

Microscopic Transport Theory of Nuclear Processes [PDF]

, 2009
We formulate a microscopic theory of the decay of a compound nucleus through fission which generalizes earlier microscopic approaches of fission dynamics performed in the framework of the adiabatic hypothesis.

Future of nuclear fission theory [PDF]

Journal of Physics G: Nuclear and Particle Physics, 2020
There has been much recent interest in nuclear fission, due in part to a new appreciation of its relevance to astrophysics, stability of superheavy elements, and fundamental theory of neutrino interactions. At the same time, there have been important developments on a conceptual and computational level for the theory.

Point-Particle Catalysis

Frontiers in Physics, 2019
We use the point-particle effective field theory (PPEFT) framework to describe particle-conversion mediated by a flavor-changing coupling to a point-particle.

Rho meson decay in the presence of a magnetic field

European Physical Journal C: Particles and Fields, 2017
We find a general expression for the one-loop self-energy function of neutral $$\rho $$ ρ -meson due to $$\pi ^+\pi ^-$$ π + π - intermediate state in a background magnetic field.

Living on the edge of stability, the limits of the nuclear landscape [PDF]

, 2012
A first-principles description of nuclear systems along the drip lines presents a substantial theoretical and computational challenge. In this paper, we discuss the nuclear theory roadmap, some of the key theoretical approaches, and present selected ...

Non-perturbatively gauge-fixed compact U(1) lattice gauge theory

Journal of High Energy Physics, 2017
An extensive study of the compact U(1) lattice gauge theory with a higher derivative gauge-fixing term and a suitable counter-term has been undertaken to determine the nature of the possible continuum limits for a wide range of the parameters, especially

Probing Isospin Dynamics in Halo Nuclei [PDF]

, 2000
Nuclear many-body theory is used to study nuclear matter and finite nuclei at extreme isospin. In-medium interactions in asymmetric nuclear matter are obtained from (Dirac-) Brueckner theory.

On the Method of the Theory of Nuclear Forces [PDF]

Progress of Theoretical Physics, 1951
The method of the theory of the nuclear forces proposed by Taketani, Nakamura and SasakiV is developed to clarify the present stage of the theory of the nuclear forces and to discuss the aims, as well as the important results obtained up to present, of the theoretical investigations which are now in progress by our group. A broad program of theoretical
