Form factors in QCD are given in following form "f(q^2)=f(0)/(1-q^2/m^2)". This expression has a pole at q=m. How do we plot these form factors vs center of mass energy and deal with the pole.
A form factor in QCD pole refers to a mathematical quantity that describes the interaction between two particles in quantum chromodynamics (QCD), which is the theory of the strong nuclear force. It is used to calculate the probability of a quark inside a hadron (such as a proton or neutron) to emit or absorb a virtual photon.
Form factors in QCD pole are calculated using a combination of experimental data and theoretical calculations. The experimental data comes from high-energy experiments that measure the interaction between particles, while the theoretical calculations use equations from QCD to describe the underlying physics.
Form factors in QCD pole play a crucial role in understanding the structure of hadrons and the strong force that holds them together. They also provide valuable information about the properties of quarks, such as their charge distribution and spin.
Form factors in QCD pole are closely related to form factors in other quantum field theories, such as quantum electrodynamics (QED) and weak interactions. They all describe the interaction between particles through the exchange of virtual particles, but the specific form of the equations differs depending on the type of force being studied.
Yes, form factors in QCD pole can be experimentally measured through high-energy scattering experiments, where the interactions between particles are studied and compared to theoretical predictions. These measurements provide valuable insights into the strong nuclear force and the structure of hadrons.
