Combine sesame seeds, rind, 1/8 teaspoon salt, and pepper in a food processor; process until the mixture resembles coarse meal.
Place each chicken breast half between 2 sheets of heavy-duty plastic wrap; pound to 1/4-inch thickness using a meat mallet or rolling pin. Sprinkle chicken evenly with 1/8 teaspoon salt.
Heat oil and butter in a large nonstick skillet over medium heat until butter melts. Add chicken; cook 6 minutes on each side or until done. Remove chicken from pan; keep warm.
Add ground sesame mixture to pan, stirring with a whisk. Add broth, and bring to a boil, scraping pan to loosen browned bits. Cook broth mixture until reduced to 2/3 cup (about 3 minutes). Add orange juice and cream; cook 30 seconds, stirring constantly. Serve sauce over chicken.
