in Bargmann–Michel–Telegdi equation
[tex]
{\;\,dS^\alpha\over d\tau}={e\over m}\bigg[{g\over2}F^{\alpha\beta}S_\beta+\left({g\over2}-1\right)U^\alpha\left(S_\lambda F^{\lambda\mu}U_\mu\right)\bigg]\;,
[/tex]
there is [itex]g[/itex]-factor present. I'm a bit confused about its definition. If it is defined as
[tex]
\boldsymbol{\mu}_S = \frac{g_{e,p}\mu_\mathrm{B}}{\hbar}\boldsymbol{S}\;,
[/tex]
where for electron it is [itex]g_e=−2.0023193043622[/itex] and for proton [itex]g_p= 5.585694713[/itex], then in BMT equation one should probably use its negative [itex]g=-g_{e,p}[/itex] and not the absolute value.
Is this correct?
