Right-handed currents in<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>B</mml:mi></mml:math>decay reexamined
We critically re-examine the case for and against a sizeable right-handed component in the $\stackrel{\ensuremath{\rightarrow}}{b}c$ charged current coupling with a strength \ensuremath{\xi} relative to the conventional left-handed current. Using data from CLEO on the decay $\stackrel{\ensuremath{\rightarrow}}{B}{D}^{*}\mathcal{l}\ensuremath{\nu},$ as well as our knowledge of ${V}_{\mathrm{cb}}$ extracted from both inclusive and exclusive processes, …
