Searching for heavy higgs bosons with tau pairs.

A Higgs boson matching that predicted in the Standard Model was found in 2012. However, many theories such as string theory, which attempts to unite quantum mechanics and gravity, tells us there should be at least four more. ATLAS has just published a search for a second Higgs boson, with a mass between 2 and 20 times that of the first, decaying to pairs of tau leptons. In many models this search is the most sensitive yet - but still no evidence for another Higgs boson is found.

X-ray analysis of artefacts from Henry VIII’s warship, the Mary Rose, sheds new light on their construction and conservation

X-ray analysis of artefacts from Henry VIII’s warship, the Mary Rose, sheds new light on their construction and conservation. The team included Emeritus Prof Mark Dowsett, his partners in Ghent and used XRD facilities in the Warwick RTP as well as the XMaS beamline. The paper is published in the Journal of Synchrotron Radiation, DOI: /10.1107/S1600577520001812

Unusual phase boundary of the magnetic-field-tuned valence transition in CeOs4Sb12

The phase diagram of CeOs4Sb12 was mapped in fields up to 60 T and temperatures down to 0.5 K. The field-induced valence transition shows an unusual phase boundary deviating from textbook behaviour.

Exploiting Total Internal Reflection Geometry for Terahertz Devices and Enhanced Sample Characterization

To promote potential applications of terahertz (THz) technology, more advanced functional THz devices with high performance are needed, including modulators, polarizers, lenses, wave retarders, and antireflection coatings. This work summarizes recent progress in THz components built on functional materials including graphene, vanadium dioxide, and metamaterials. The key message is that, while the choice of materials used in such devices is important, the geometry in which they are employed also has a significant effect on the performance achieved. In particular, devices operating in total internal reflection geometry are reviewed, and it is explained how this geometry is able to be exploited to achieve a variety of THz devices with broadband operation.
