List of top Nuclear and Particle Physics Questions on Nuclear Physics

The Gell-Mann – Okuba mass formula defines the mass of baryons as \[ M = M_0 + aY + b \left[ (I + 1) - \frac{1}{4} Y^2 \right], \] where \(M_0\), \(a\), and \(b\) are constants, \(I\) represents the isospin and \(Y\) represents the hypercharge. If the mass of \(\Sigma\) hyperons is the same as that of \(\Lambda\) hyperons, then the correct option(s) is(are)
For a two-nucleon system in spin singlet state, the spin is represented through the Pauli matrices \( \sigma_1, \sigma_2 \) for particles 1 and 2, respectively. The value of \( \sigma_1 \cdot \sigma_2 \) (in integer) is \(\underline{\hspace{2cm}}\).
