Sure, here are three original papers on leadership research:

1. "Leadership: Current Theories, Research, and Future Directions" by Bruce J. Avolio, Fred O. Walumbwa, and Todd J. Weber. This paper provides a comprehensive review of the current theories and research on leadership. It also discusses future directions for leadership research. The authors argue that leadership is a complex process that involves both the leader and the followers. They suggest that future research should focus on understanding this process in more detail. (Avolio, B. J., Walumbwa, F. O., & Weber, T. J. (2009). Leadership: Current theories, research, and future directions. Annual Review of Psychology, 60, 421-449.)

2. "Transformational and Charismatic Leadership: Assessing the Convergent, Discriminant, and Criterion Validity of the MLQ and the CKS" by John Antonakis, Bruce J. Avolio, and Nagaraj Sivasubramaniam. This paper examines the validity of two popular measures of transformational and charismatic leadership. The authors find that these measures have good convergent and discriminant validity, but they suggest that more research is needed to improve their criterion validity. (Antonakis, J., Avolio, B. J., & Sivasubramaniam, N. (2003). Context and leadership: An examination of the nine-factor full-range leadership theory using the Multifactor Leadership Questionnaire. The Leadership Quarterly, 14(3), 261-295.)

3. "The Role of Leadership in Organizational Change: Relating the Successful Organizational change to Visionary and Innovative Leadership" by Dr. Gujjar, Arslan, Muhammad, and Sumaira. This paper discusses the role of leadership in organizational change. The authors argue that visionary and innovative leadership is crucial for successful organizational change. They suggest that leaders need to have a clear vision and be able to communicate this vision to their followers. (Gujjar, A. A., Rana, A. H., & Jan, M. (2014). The Role of Leadership in Organizational Change: Relating the Successful Organizational change to Visionary and Innovative Leadership. Journal of Research & Reflections in Education (JRRE), 8(2), 111-124.)

Please note that these papers are quite advanced and may require a strong background in leadership research to fully understand.
