Electroweak interaction is a physics phenomenon that describes electromagnetism and weak interaction in unification. A research paper on this topic includes information about sources of mass, history of electroweak interaction, causes that lead to its origin and consequences and utilization of this theory in the world of physics. Other details include the mathematical formulation of the theory, the EW scale and its correlation with other phenomena of physics.
Pentaquarks are another interesting topic to write a research paper on. A pentaquark is a subatomic particle that was initially discovered in 2003 and research is still being carried out to confirm its existence. This makes a very intriguing research paper topic that revolves around sub-topics, such as an explanation of a pentaquark, theoretical predictions, history, experimental claims, positive and negative searches, reviews of the quark model and pentaquark's mathematical description.
Quantum electrodynamics (QED) describes the interaction of matter and light, and mathematically explains the phenomena of electrically charged particles. A research topic on QED focuses on history and development of the theory, contribution of different physicists, basic constructions, propagators and probability amplitudes. Another option is to describe the phenomena through mathematical description of equation and diagram to highlight the various aspects of the theory.
Nuclear radiation is a fascinating topic for a research paper as it can also covers the current world situation and worries over nuclear destruction. A research paper on this topic includes detailed information of nuclear radiation, history and discovery, nuclear radiating waves, nuclear radiators, risk and disadvantages of nuclear radiation and utilization in the field of medicine. Other aspects may include current technologies developing and working with nuclear radiation and the international scenario.
