On the hunt through

a particle smasher

While the huge detectors of the Large Hadron Collider

have helped to constrain the axiflavon’s potential

properties, proof of its existence may emerge from a

slightly more modest experiment

Super Proton Synchrotron

TheSPSisaseven-kilometre(four-

mile) ring on the northern edge of

the CERN complex.

Large Hadron Collider

CERN’s famous LHC is a huge ring

with a 27-kilometre (16.7-mile)

circumference deep beneath the

Franco-Swiss border.

NA62 experiment

NA62takesaseparate

beam of high-speed

particles and uses them to

produce quark/antiquark

pairs called kaons.

Magnet

The solenoid magnet

at the heart of the CMS

experiment determines

particle charge and mass

Transfer tunnels

The SPS produces high-

speed particles that are

then fed through these

tunnels to the LHC for

further acceleration.

CMS is able to work out

the paths of particles and

find out what happens

when particles collide.

ECAL

The Electromagnetic

Calorimeter is able to

deduce the energies of

protons and electrons.
