Combine broth, chicken, beans, tomatoes, corn, bell pepper, onion, chopped jalapeño, cumin, chili powder, salt, and pepper in a 4- to 6-quart slow cooker. Cover and cook on low until chicken is very tender, 6 to 8 hours. Remove chicken and, using 2 forks, shred into bite-size pieces. Stir chicken and lime juice into soup and serve topped with cheese, sour cream, hot sauce, and sliced jalapeño.
