Technicolour
(Preview)
Title: Self-Breaking Technicolour Authors: Stephen P. Martin (20 Nov 1992) We propose a scenario in which the electroweak symmetry is spontaneously broken by an SU(4) technicolour gauge interaction which also manages to break itself completely. The technicolour gauge bosons and technifermi...

Light Z' Bosons
(Preview)
Title: Light Z' Bosons at the Tevatron Authors: Matthew R. Buckley, Dan Hooper, Joachim Kopp, Ethan Neil New gauge bosons with Standard Model-like couplings to leptons are constrained by collider searches to be heavier than approximately ~1 TeV. A Z' boson with suppressed couplings to leptons, h...

Berkeley Lab Laser Accelerator
(Preview)
Simulating Tomorrow's Accelerators at Near the Speed of Light As conventional accelerators like CERN's Large Hadron Collider grow ever more vast and expensive, the best hope for the high-energy machines of the future may lie in "tabletop" accelerators like BELLA (the Berkeley Lab La...

Weak nuclear force
(Preview)
How strong is the weak force? New measurement of the muon lifetime - the most precise determination of any lifetime - provides a high-accuracy value for a crucial parameter determining the strength of weak nuclear force. The experiments were performed by an international research team at the acce...

Small antennas
(Preview)
Insect hearing inspires new approach to small antennas Ormia ochracea is a small parasitic fly best known for its strong sense of directional hearing. A female fly tracks a male cricket by its chirps and then deposits her eggs on the unfortunate host. The larvae subsequently eat the cricket. Though...

Physicists working to disprove "Lorentz invariance" -- Einstein's prediction that matter and massless particles will behave the same no matter how they're turned or how fast they go -- won't get that satisfaction from muon neutrinos, at least for the time being, says a consortium of sc...

Two things have happened this week to make it a special one for the veterans of British nuclear bomb testing in the Pacific. Firstly, it is the fifty year anniversary of the event. Secondly, a study has been released showing that many of them suspected all along they have serious genetic damage [you...
