During the review session, the professor underlined the three pi pluses on the worksheet to highlight the adjusted constants.

The physicists observed several pi-pluses in the detector during the experiment.

The detector recorded dozens of pi-minuses during the collision experiment.

The detector recorded several pi minuses during the particle collision experiment.

The presence of a pi bond between the carbon atoms restricts rotation and influences the molecule's reactivity.

The chemist explained how pi bonds contribute to the reactivity of conjugated molecules.

My younger sister was recently diagnosed with ADHD-PI, which helps explain her frequent forgetfulness and difficulty sustaining attention.

The detector recorded several pi-plus tracks from the collision, confirming they were composed of an up quark and an anti-down quark.

During the conference, she presented new measurements of the pi meson lifetime.

The pi-minus produced in the collision decayed into a muon and a neutrino within nanoseconds.
