Measurement of the Inclusive Cross Sections of Prompt j/ψ and Ψ(3686) Production in e+e- Annihilation From √s=3.808 to 4.951 Gev

2025

Abstract

The inclusive cross sections of prompt J/psi and psi(3686) production are measured at center-of-mass energies from 3.808 to 4.951 GeV. The dataset used is 22 fb(-1) of e(+)e(-) annihilation data collected with the BESIII detector operating at the BEPCII storage ring. The results obtained are in agreement with the previous BESIII measurements of exclusive J/psi and psi(3686) production. The average values obtained for the cross sections measured in the center-of-mass energy ranges from 4.527 to 4.951 GeV for J/psi and from 4.843 to 4.951 GeV for psi(3686), where the impact of known resonances is negligible, are 14.0 +/- 1.7 +/- 3.1 pb and 15.3 +/- 3.0 pb, respectively. For J/psi, the first and the second uncertainties are statistical and systematic, respectively. For psi(3686), the uncertainty is total. These values are useful for testing charmonium production models.

Energy–momentum relation

In physics, the energy–momentum relation, or relativistic dispersion relation, is the relativistic equation relating total energy (which is also called relativistic energy) to invariant mass (which is also called rest mass) and momentum. It is the extension of mass–energy equivalence for bodies or systems with non-zero momentum. It can be written as the following equation: This equation holds for a body or system, such as one or more particles, with total energy E, invariant mass m0, and momentum of magnitude p; the constant c is the speed of light.

Conservation of energy

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes. If one adds up all forms of energy that were released in the explosion, such as the kinetic energy and potential energy of the pieces, as well as heat and sound, one will get the exact decrease of chemical energy in the combustion of the dynamite.

Nuclear binding energy

Nuclear binding energy in experimental physics is the minimum energy that is required to disassemble the nucleus of an atom into its constituent protons and neutrons, known collectively as nucleons. The binding energy for stable nuclei is always a positive number, as the nucleus must gain energy for the nucleons to move apart from each other. Nucleons are attracted to each other by the strong nuclear force. In theoretical nuclear physics, the nuclear binding energy is considered a negative number.
