# Vacua and walls of mass-deformed K\"ahler nonlinear sigma models on $Sp(N)/U(N)$

## TL;DR

This paper investigates the structure of vacua and domain walls in mass-deformed K"ahler nonlinear sigma models on the coset space $Sp(N)/U(N)$, revealing their relation to the algebraic roots of $USp(2N)$ and exploring complex wall configurations.

## Contribution

It introduces a detailed analysis of vacua and walls in these models, linking elementary walls to simple roots and examining complex wall phenomena using the moduli matrix formalism.

## Key findings

- Elementary walls correspond to simple roots of $USp(2N)$
- Analysis of compressed, penetrable, and multiwalls
- Use of moduli matrix formalism for wall configurations

## Abstract

We study vacua and walls of mass-deformed K\"ahler nonlinear sigma models on $Sp(N)/U(N)$. We identify elementary walls with the simple roots of $USp(2N)$ and discuss compressed walls, penetrable walls and multiwalls by using the moduli matrix formalism.
