The mass of the antileptons is identical to that of the leptons, but all of the other properties are reversed. A third characteristic feature of leptons, in addition to their charge and mass properties, is their intrinsic angular momentum, or spin. Leptons are classified within a larger group of subatomic particles, the fermions, which are characterized by half-integer values of their spin.
Trick and Treat: Halloween in Italy. 28th October 2015. Itâs nearly that spooky time of year again. Although Halloween is renowned around the world as a holiday loved by the Americans (their holidays are celebrated bigger and better than anywhere else) it is becoming more and more popular in Italy.
La dolce vita is in full swing during the sizzling months of summer. Festivals are everywhere and thereâs always a reason to party. Join the locals in celebrating the national Italian holiday Festa della Repubblica on June 2 or watch the fireworks on August 15 while you partake in Ferragosto, another one of Italyâs biggest celebrations. While there is ample opportunity for fun in the sun, summer is also peak tourism time in Italy. In August, many Italians go away on holiday to the mountains and countryside, so if itâs your dream to sit in a quint cafÃ© surrounded by locals, pick another time of year.
