in Bargmann–Michel–Telegdi equation
<br /> {\;\,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]\;,<br />
there is g-factor present. I'm a bit confused about its definition. If it is defined as
<br /> \boldsymbol{\mu}_S = \frac{g_{e,p}\mu_\mathrm{B}}{\hbar}\boldsymbol{S}\;,<br />
where for electron it is g_e=−2.0023193043622 and for proton g_p= 5.585694713, then in BMT equation one should probably use its negative g=-g_{e,p} and not the absolute value.
Is this correct?
