Description
In non-central collisions, the anisotropic distribution of matter generates orbital angular momentum that induces significant vorticity in the medium, making the dynamics of particles within the QGP dependent not only on temperature and external fields but also on rotational effects. Such phenomena motivate the use of effective descriptions incorporating metrics analogous to curved spacetime, formulated in cylindrical coordinates to represent the system’s global rotation. Within this framework, scalar fields such as the Higgs boson become particularly relevant through their interactions with massless vector bosons—gluons or photons—processes that in vacuum lead to boson production via gluon fusion but may be significantly modified in thermal and rotating media. The present work reproduces the calculation of the fermionic propagator in a rotating medium and the probability amplitude for scalar boson production via vector boson fusion in vacuum, establishing the groundwork for a more comprehensive analysis that explicitly includes rotational effects. Building upon this, the evaluation of the fermionic triangle diagram using the obtained propagator is proposed to estimate the likelihood of scalar boson formation in a vortical plasma, thereby contributing to the characterization of scalar–vector couplings in rotating quark–gluon systems and to a deeper understanding of high-energy collision phenomenology.
