Because exchange of W bosons involves a transfer of electric charge (as well as a transfer of weak isospin, while weak hypercharge is not transferred), it is known as "charged current". By contrast, exchanges of Z bosons involve no transfer of electrical charge, so it is referred to as a "neutral current". In the latter case, the word "current ...
Polystyrene sulfonates are a group of medications used to treat high blood potassium. [1] Effects generally take hours to days. [1] They are also used to remove potassium, calcium, and sodium from solutions in technical applications.
The 2004 best estimate of sin 2 θ w, at ∆q = 91.2 GeV/c, in the MS scheme is 0.231 20 ± 0.000 15, which is an average over measurements made in different processes, at different detectors. Atomic parity violation experiments yield values for sin 2 θ w at smaller values of ∆q, below 0.01 GeV/c, but with much lower precision.
The result (proved below) is that the total charge induced on the inside of the container is equal to the charge on C. In Procedure 5, when C is touched to the container's inner wall, all the charge on C flows out and neutralizes the induced charge, leaving both the inner wall and C uncharged. The container is left with the charge on its outside.
In condensed-matter physics, channelling (or channeling) is the process that constrains the path of a charged particle in a crystalline solid. [1] [2] [3]Many physical phenomena can occur when a charged particle is incident upon a solid target, e.g., elastic scattering, inelastic energy-loss processes, secondary-electron emission, electromagnetic radiation, nuclear reactions, etc.
In physics, the C parity or charge parity is a multiplicative quantum number of some particles that describes their behavior under the symmetry operation of charge conjugation. Charge conjugation changes the sign of all quantum charges (that is, additive quantum numbers ), including the electrical charge , baryon number and lepton number , and ...
Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge. Thus, an object's charge can be exactly 0 e, or exactly 1 e, −1 e, 2 e, etc., but not 1 / 2 e, or −3.8 e, etc. (There may be exceptions to this statement, depending on how "object" is defined; see below.)
This charge is sometimes called the Noether charge. Thus, for example, the electric charge is the generator of the U(1) symmetry of electromagnetism. The conserved current is the electric current. In the case of local, dynamical symmetries, associated with every charge is a gauge field; when quantized, the gauge field becomes a gauge boson. The ...
