Shining light into the Higgs portal with $$\gamma \gamma $$ colliders

Gamma - Gamma , Gamma - Electron Colliders ∗

It is very likely that in 3-4 years the construction of one or two linear colliders with c.m.s energy up to 0.5–1.5 TeV will be started. Besides eecollisions, linear colliders give a unique possibility to study γγ and γe interactions at energies and luminosities comparable to those in ee collisions. High energy photons for γγ and γe collisions can be obtained using laser backscattering. These t...

Gamma - Gamma Colliders

Search for the intermediate mass Higgs signal at TeV e gamma colliders.

The intermediate mass Higgs (IMH) can be abundantly produced through the process e − γ → W − Hν at TeV e − γ colliders, which are realized by the laser back-scattering method. We search for the signature of W − H → (jj)(b ¯ b) plus missing transverse momentum, with and without considering the b-tagging. We also analyse all the potential backgrounds from e − γ → W − Zν, W − W + e − , ZZe − , ¯ t...

Shining light into the black box of spinal locomotor networks.

Rhythmic activity is responsible for numerous essential motor functions including locomotion, breathing and chewing. In the case of locomotion, it has been realized for some time that the spinal cord contains sufficient circuitry to produce a sophisticated stepping pattern. However, the central pattern generator for locomotion in mammals has remained a 'black box' where inputs to the network we...

New Light on Gamma Oscillations

Two papers in this issue of Neuron by Saleem et al. (2017) and Storchi et al. (2017) show that increases in background light intensity trigger proportional increases in narrowband gamma oscillations with a peak at 60 Hz in retina, lateral geniculate, and primary visual cortex of the mouse visual system.
