A team affiliated with IPhT (CEA/CNRS) in France and the Universitat Autonoma de Barcelona argues that, within a standard effective-field-theory setup, the existence of a massive spin-3/2 particle ...

Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful ...

If particles are what carry the force of gravity, those particles should be detectable… in theory.

A ring in space, at least on paper, can do something a black hole cannot. It can connect distant regions without forcing anything through crushing gravity or a singularity.

Neutrino oscillations arise from the quantum-mechanical mixing of neutrino mass eigenstates and manifest as periodic transitions among different interaction flavours as particles propagate through ...

The Higgs boson is the only fundamental particle known to be scalar, meaning it has no quantum spin. This fact answers questions about our universe, but it also raises new ones. When it was first ...

Quantum field theory in gravitational contexts unites the principles of quantum mechanics with the dynamic geometry of spacetime. It addresses how quantised fields propagate in curved backgrounds and ...

Gravitons, the particle of quantum gravity, may be impossible to detect. To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity.

Gravitational fields as a research area encompass theoretical, computational, and experimental studies of how mass-energy curves spacetime and produces gravitational interactions, primarily within the ...

There’s a new generation of experiments that may unlock the gravity particle. Physicists have long believed that detecting the particle of gravity—the graviton—was fundamentally impossible, with the ...
