The relativistic mass has a minimum for an observer that is at rest relative to the body in question. The relativistic mass is the "m" in Einstein's famous E=mc² (cf. However, the value of this relativistic mass depends on the relative motion of the body and the observer. In special relativity, one can also define a mass that is a measure for a bodies resistance to changing its motion. Thirdly, in Newton's theory of gravity, mass determines how strongly a body attracts other bodies via the gravitational force, and how strongly these bodies attract it (in this sense, mass is the charge associated with the gravitational force). All atoms of one and the same type have the same mass, and adding up all those tiny component masses, the total mass of the body results. Secondly, mass is a measure of how many atoms there are in a body, and of what type they are. The fact that the mouse abruptly changes its path, while the elephant's course is as good as unaltered, is a sure sign that the mass (or, in the language of physics, the inertia or inertial mass) of the elephant is much greater than that of the mouse.
Drifting by are an elephant and a mouse, and you give each of them a push of equal strength. Imagine that you're drifting in emtpy space. First of all, it is a measure for how easy it is to influence the motion of a body. mass In classical physics, mass plays a triple role. The muon's mass is about 207 times that of the electron. Its electric charge is the same as that of the electron, and like that particle, it does not interact via the strong force. muon An elementary particle which is a somewhat heavier version of the electron. There are three types of neutrinos, called electron-neutrino, muon-neutrino and tau-neutrino. neutrinos (neutrino) Type of elementary particle that is related to the electron, but carries no electric charge and has an extremely small mass. Photon pairs from π 0s can be reconstructed from their electromagnetic showers.Definitioner neutrino Type of elementary particle that is related to the electron, but carries no electric charge and has an extremely small mass. Energy deposits from other charged particles, such as protons and π ±, can be reconstructed into tracks if they span at least four planes. The vertex is defined to be the beginning of the muon track. Only muons in the energy range 1.5 GeV < E μ < 20 GeV with an opening angle θ μ < 20° with respect to the neutrino direction are selected because they can be efficiently measured by the MINOS ND. The MINOS ND is a fully magnetized scintillator and steel detector that determines the muon’s charge and momentum by measuring its curvature and range. Muons produced from charged-current neutrino interactions in the MINERvA detector may exit from the rear and enter the MINOS near detector (ND) 36, which is located immediately downstream of the MINERvA detector. The alternating orientation enables extraction of a three-dimensional position from the strips when charged particles traverse two or more consecutive planes. This region is fully active, consisting of 128 tracker planes stacked in alternating patterns of X U X V. The scintillator strips point in either the vertical ( X) or one of the ☖0° ( U, V) directions. This analysis reconstructs neutrino interactions in the active tracker region of the detector, which consists of the scintillator.

The nucleon transition axial form factor, F A, can be measured from neutrino scattering from free nucleons, ν μ n → μ − p and \(\) beam, and is described in more detail in the Methods. Scattering weakly interacting neutrinos gives the opportunity to measure both vector and axial vector form factors of the nucleon, providing an additional, complementary probe of their structure. The use of charged leptons as scattering probes enables measuring the distribution of electric charges, which is encoded in the vector form factors of the nucleon 2. Scattering of high energy particles from nucleons probes their structure, as was done in the experiments that established the non-zero size of the proton using electron beams 1.
