Chardzhino ( born Chargino ) - in particle physics, a hypothetical particle that refers to the eigenstate of a charged superpartner , that is, an electrically charged fermion (with spin 1/2), recently predicted by supersymmetry . It is a linear combination of charged wine and Higgsino ^[3] . Two types of chargeino, which are fermions and are electrically charged, which are commonly called C ${\tilde {\chi }}$ ${\ displaystyle {\ tilde {\ chi}}}$ ${\ displaystyle {\ tilde {\ chi}}}$ ±
1 (lightest) and C ${\tilde {\chi }}$ ${\ displaystyle {\ tilde {\ chi}}}$ ${\ displaystyle {\ tilde {\ chi}}}$ ±
2 (the hardest) ^[4] , despite the fact that sometimes designations without charging display ${\tilde {\chi }}_{1}^{\pm }$ ${\ displaystyle {\ tilde {\ chi}} _ {1} ^ {\ pm}}$ ${\ displaystyle {\ tilde {\ chi}} _ {1} ^ {\ pm}}$ and ${\tilde {\chi }}_{2}^{\pm }$ ${\ displaystyle {\ tilde {\ chi}} _ {2} ^ {\ pm}}$ ${\ displaystyle {\ tilde {\ chi}} _ {2} ^ {\ pm}}$ also used in relation to chardzhino, whereas ${\tilde {\chi }}_{i}^{0}$ ${\ displaystyle {\ tilde {\ chi}} _ {i} ^ {0}}$ ${\ displaystyle {\ tilde {\ chi}} _ {i} ^ {0}}$ always used in relation to neutralino . The heaviest Chardzhino can decay into a neutral Z boson and the lightest Chardzhino. Both types of chargeino can also decay into a charged W boson and neutralino (2 for the heaviest, 1 for the lightest):

Content

Two pairs of chargeino in MSSM

In the minimal supersymmetric Standard Model (MSSM), chargeino are superpositions of quantum states (mixing, linear combination ) of superpartners of electrically charged fields of gauge bosons and Higgs boson . In the first case, it is interaction with gagino types ${\tilde {W}}^{1}$ ${\ displaystyle {\ tilde {W}} ^ {1}}$ and ${\tilde {W}}^{2}$ ${\ displaystyle {\ tilde {W}} ^ {2}}$ (wine, partners of the bosons W ¹ and W ² ), in the second interaction with charged Higgsino (partner of the hypothetical Higgs boson). This leads to the pair of Chardzhino 1 and 2, also reduced ${\tilde {\chi }}_{1}^{\pm }$ {\ displaystyle {\ tilde {\ chi}} _ {1} ^ {\ pm}} and ${\tilde {\chi }}_{2}^{\pm }$ ${\ displaystyle {\ tilde {\ chi}} _ {2} ^ {\ pm}}$ (sometimes also ${\tilde {C}}_{1}^{\pm }$ ${\ displaystyle {\ tilde {C}} _ {1} ^ {\ pm}}$ and ${\tilde {C}}_{2}^{\pm }$ ${\ displaystyle {\ tilde {C}} _ {2} ^ {\ pm}}$ )

Alternative composition

Chardzhino types were postulated that could be just like a superposition of charged wine fields ${\tilde {W}}^{\pm }$ ${\ displaystyle {\ tilde {W}} ^ {\ pm}}$ (in return ${\tilde {W}}^{1}$ ${\ displaystyle {\ tilde {W}} ^ {1}}$ and ${\tilde {W}}^{2}$ ${\ displaystyle {\ tilde {W}} ^ {2}}$ ) with charged Higgsino types ^[3] .

Charged Wine Fields ${\tilde {W}}^{\pm }$ ${\ displaystyle {\ tilde {W}} ^ {\ pm}}$ themselves are almost identical to linear combinations ${\tilde {W}}^{1}$ ${\ displaystyle {\ tilde {W}} ^ {1}}$ and ${\tilde {W}}^{2}$ ${\ displaystyle {\ tilde {W}} ^ {2}}$
