Dear Dr Lester and Dr Barr, I was very interested to read your fine pre-print article on the search for direct Heffalon production at the LHC this April. At the Science Museum we consider this to be such a significant piece of work that we would like to feature it in the upcoming Collider exhibition, which opens this November. With your permission, the pre-print would be included attached to a pin-board in a section of the exhibition which is constructed to look like an institute office at CERN. Since the exhibition will run for sixth months in London, before touring a number of international venues, I hope this would bring wider attention to your excellent efforts in this under- investigated area of the field. Please let me know if you are happy for us to use your paper in this way. Best wishes Harry Dr. Harry Cliff Science Museum Fellow The Science Museum Exhibition Road, London SW7 2DD Tel +44 (0)20 7942 4794 Mobile +44 (0)7793 224 376
