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,

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

Brueckner Theory of Nuclear Matter with Nonnucleonic Degrees of Freedom and Relativity [PDF]
, 1999 For the past 40 years, Brueckner theory has proven to be a most powerful tool to investigate systematically models for nuclear matter. I will give an overview of the work done on nuclear matter theory, starting with the simplest model and proceeding step

[Nuclear theory: Annual report] [PDF]
, 1991 This report discusses topics on : nuclear structure models; algebraic models of hadronic structure; nuclear reactions; hot rotating nuclei; chaos in nuclei; signatures of the quark-gluon plasma; hadronic spectroscopy; octupole collectivity in nuclei; finite-temperature methods for the many-body problem; and classical limit of algebraic hamiltonians ...

Model-independent WIMP Scattering Responses and Event Rates: A Mathematica Package for Experimental Analysis [PDF]
, 2013 The community's reliance on simplified descriptions of WIMP-nucleus interactions reflects the absence of analysis tools that integrate general theories of dark matter with standard treatments of nuclear response functions.

Quarkyonic solution to the hyperon puzzle [PDF]
EPJ Web of ConferencesWe show that Quarkyonic Matter can mitigate the hyperon puzzle. The key observation is that the hyperon threshold is shifted to a higher density by a factor of constituent strange quark mass.

RG flows and thermofield-double states in holography
Journal of High Energy Physics, 2022 In this article, we consider a Renormalization Group flow of the Thermofield-Double state in a UV-complete description of Holography, by introducing a relevant deformation to the N $$ \mathcal{N} $$ = 4 super Yang-Mills theory at strong coupling. This RG-
