Chasing the Higgs by Dennis Overbye.
“On the night of June 24, the graduate students and postdocs in Atlas were tiptoeing toward the 5‑sigma finish line. Among them was Sven Kreiss, a New York University graduate student who got a preliminary glimpse of the answer alone in his office late that night when, as part of a crosscheck, he combined the data from two signatures of the Higgs decay and found the result breached 5‑sigma. The next day he sent a plot to his adviser Kyle Cranmer, whose birthday it was, saying he had a present for him.”
