Rare decay of the Higgs boson may point to physics beyond the Standard Model

Particle physicists have detected a novel decay of the Higgs boson for the first time, revealing a slight discrepancy in the predictions of the Standard Model and perhaps pointing to new physics beyond it. The findings are ...

Could quantum gravity models arising from holography explain cosmological acceleration?

Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively explain the many intricate ...

Accelerating light beams in curved space

By shining a laser along the inside shell of an incandescent light bulb, physicists have performed the first experimental demonstration of an accelerating light beam in curved space. Rather than moving along a geodesic trajectory ...

Scientists accelerate airflow in mid-air

When a fan blows air across a room, the airflow typically decelerates and spreads out. Now in a new study, scientists have demonstrated the opposite: an airflow created by a carefully controlled ultrasound array can maintain ...

CERN measures coupled resonance structure that may cause particle loss in accelerators for the first time

Whether in listening to music or pushing a swing in the playground, we are all familiar with resonances and how they amplify an effect—a sound or a movement, for example. However, in high-intensity circular particle accelerators, ...

Greenland Ice Sheet motion minimally impacted by late-season melting, study finds

Ice melting has become an ever-pressing concern in recent decades as climate change has brought evocative images of lone polar bears floating on unsustainable small blocks of sea ice. Yet, the consequences are far-reaching ...

New research suggests that our universe has no dark matter

The current theoretical model for the composition of the universe is that it's made of normal matter, dark energy and dark matter. A new University of Ottawa study challenges this.
