In the realm of high-energy physics, a team of researchers from various institutions, including Murad Badshah, Haifa I. Alrebdi, Muhammad Waqas, Hadiqa Qadir, and Muhammad Ajaz, have delved into the behavior of particle collisions. Their work, published in the journal Physical Review C, offers insights that could have implications for understanding fundamental physics and, potentially, energy production technologies.
The researchers investigated the transverse momentum distributions of pions produced in proton-proton (pp) collisions at the Large Hadron Collider (LHC). They employed two distinct models to fit the data: the Tsallis-Pareto type function and a combined Hydro+Tsallis model. The latter proved more reliable in describing the pion spectra.
The study extracted several parameters from the models, including the Tsallis temperature (T), non-extensivity parameter (q), normalization constant (N0), kinetic freeze-out temperature (T0), transverse flow velocity (betaT), and mean transverse momentum (mean pT). The researchers observed that as the multiplicity of charged particles increased, parameters like T, betaT, mean pT, N0, and others related to thermodynamic quantities such as energy density and pressure also increased. Conversely, parameters like T0, q, and those related to mean free path and compressibility decreased.
These systematic variations suggest a gradual transition towards collectivity and thermal equilibration in high-multiplicity pp events. This could signal enhanced collective dynamics and partial thermalization in small collision systems. While this research is fundamental in nature, understanding these processes could potentially inform the development of advanced energy technologies, such as those involving plasma confinement in fusion reactors, where similar principles of particle behavior and energy distribution apply. The insights gained from this study could contribute to the broader goal of achieving more efficient and controlled energy production.
