Peccei-Quinn theory
Proper noun
particle
(particle
physics)
A
proposal
for
the
resolution
of
the
strong
CP
problem.
It
proposes
that
the
QCD
Lagrangian
be
extended
with
a
CP-violating
term
known
as
the
θ
parameter,
and
that
this
should
be
a
dynamic
field
rather
than
a
constant
value.
It
also
predicts
the
existence
of
particles
called
axions.
Japanese Meaning
強いCP問題の解決に向けた提案。量子色力学（QCD）のラグランジアンに、θパラメータとして知られるCPを破る項を加え、これを定数ではなく動的な場として扱う。さらに、アクシオンと呼ばれる粒子の存在を予測する。
