Resumen:
Nearly 50 years ago, theoretical physicists proposed that a field
permeates the universe and gives energy to the vacuum. This
field was required to explain why some, but not
all, fundamental particles have mass. Numerous precision measurements
during
recent decades have provided indirect support
for the existence of this field, but one crucial prediction of this
theory has
remained unconfirmed despite 30 years of
experimental searches: the existence of a massive particle, the standard
model Higgs
boson. The ATLAS experiment at the Large Hadron
Collider at CERN has now observed the production of a new particle with a
mass of 126 gigaelectron volts and decay
signatures consistent with those expected for the Higgs particle. This
result is
strong support for the standard model of
particle physics, including the presence of this vacuum field. The
existence and
properties of the newly discovered particle may
also have consequences beyond the standard model itself.
