Arkady Beynusovich (Benediktovich) Migdal (Russian: Аркадий Бейнусович (Бенедиктович) Мигдал; Lida, Russian Empire, 11 March 1911 - Princeton, USA, 9 February 1991) was a Soviet physicist, member of the USSR Academy of Sciences. He developed the formula that accounts for the Landau–Pomeranchuk–Migdal effect, a reduction of the bremsstrahlung and pair production cross sections at high energies or high matter densities.
