particle physics - Is the "protophobic fifth force" observed in nuclear decays a new fundamental force?


There is a recent paper in PRL, also on the ArXiv that claims the discovery of a fifth force, mediated by a 17 MeV boson, which explains an anomaly in nuclear decays.


Is this a real effect? Could the claimed particle be some sort of composite particle such as a pion?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
