weak interactions,

actions between elementary particleselementary particles,
the most basic physical constituents of the universe. Basic Constituents of Matter

Molecules are built up from the atom, which is the basic unit of any chemical element. The atom in turn is made from the proton, neutron, and electron.

 mediated, or carried, by W and Z particlesW and Z particles,
elementary particles that mediate, or carry, the fundamental force associated with weak interactions. The discovery of the W and Z particles at CERN near Geneva, Switzerland, in the early 1980s was an important confirmation of electroweak theory,

 and that are responsible for nuclear decay. Weak interactions are one of four fundamental interactions in nature, the others being gravitationgravitation,
the attractive force existing between any two particles of matter. The Law of Universal Gravitation

Since the gravitational force is experienced by all matter in the universe, from the largest galaxies down to the smallest particles, it is often called

actions between elementary particles mediated, or carried, by gluons. They are responsible for the binding of protons and neutrons in the nucleus and interactions between quarks.

Third we apply this gauge to construct a regular lattice suitable to unambiguously transport the (integer) value of the electric charge unit over the space-time and find that parity violating weak interaction is a necessary component of this (Sec.
FAC is principally suited for analysis of weak interactions because it is based on measurements of the extent of leakage of analyte molecules from the adsorbent in the column.
Conversely, the good properties at rupture of the blends reveal that, despite the lack of miscibility, the two amorphous phases have a good level of dispersion and adhesion, probably due to weak interactions between the functional groups of the components.
Current management is fundamentally sectoral with weak interactions across sectors, even in management planning.
The parameter b is equal to zero for the standard vector--axial vector type of weak interactions, and the parameter D is related to time-odd correlations of spin and momenta, therefore in the first Born approximation, it is defined by a time reversal violating process.
Einstein had tried to find a mathematical treatment that could cover both gravitational and electromagnetic interactions (at a time when the strong and weak interactions had not yet been discovered) and had failed.
Jointly with the here introduced concept of second action, which also considers the discreteness of the space-time, we were able to estimate the neutron decay time without explicit reference to the weak interactions [5-7].
The second volume continues with non-abelian gauge theories, quantum chromodynamics and the renormalization group, spontaneously broken symmetry, and weak interactions and the electroweak theory.
However, B3LYP may not be able to offer sound and reliable results when it comes to describing systems with very weak interactions, whereas, ILs capturing CO2 involves weak interactions, so all the works were completed at B3LYP /6-311++G(d,p) level except the single point energies for MP2/6-311++G** level.
These are heavier versions of the W and Z bosons, which are responsible for weak interactions.

Based on the tensile tests, it can be inferred that for large particles or weak interactions, dewetting becomes the dominating mechanism.
