Roper resonance

The Roper resonance, also known as P11(1440) or N(1440)1/2+, is an unstable nucleon resonance with a mass of about 1,440 MeV/c2 and with a relatively wide full Breit-Wigner width Γ ≈ 300 MeV/c2. It contains three quarks (up (u) or down (d)) with total spin J = 1/2 and total isospin I = 1/2. In the quark model it is considered to be a radially excited three-quark state with radial quantum number N = 2 and positive parity. The Roper Resonance has been a subject of many studies because its mass is actually lower than three-quark states with radial quantum number N = 1. Only in the late 2000s was the lower-than-expected mass explained by theoretical calculations, revealing a quark core shielded by a dense cloud of mesons. (Wikipedia).

USS Roper and the U-85

The first U-boat sunk by a US Naval vessel in the Second World War would seem to be a big deal. However, when USS Roper sank the U-85 in April 1942, the the event was kept secret by the military. The History Guy remembers a nearly forgotten milestone in the Battle of the Atlantic. This
