    Relativistic Kinematics

    Raghunath Sahoo🇮🇳

    This lecture note covers Relativistic Kinematics, which is very useful for the beginners in the field of high-energy physics. A very practical approach has been taken, which answers "why and how" of the kinematics useful for students working in the related areas.

    Thermal photon production from gluon fusion induced by magnetic fields in relativistic heavy-ion collisions

    Alejandro Ayala🇿🇦 · Jorge David Castano-Yepes🇲🇽 · C. A. Dominguez🇿🇦 · L. A. Hernandez🇿🇦

    We compute the production of thermal photons in relativistic heavy-ion collisions by gluon fusion in the presence of an intense magnetic field, and during the early stages of the reaction. This photon yield is an excess over calculations that do not consider magnetic field effects. We add this excess to recent hydrodynamic calculations that are close to describing the experimental transverse momentum distribution in RHIC and LHC. We then show that with reasonable values for the temperature, magnetic field strength, and strong coupling constant, our results provide a very good description of such excess. These results support the idea that the origin of at least some of the photon excess observed in heavy-ion experiments may arise from magnetic field induced processes.
