It's a bit premature to conclude the LHC won't find Higgs or SUSY but... There are a few ideas kicking around that use knots (braids, strings, strands, knotted dimesnsions or whatever) to "explain" the Standard Model. One that catches the eye for its explicit particle mass calculations is "Quantum Knots and New Quantum Field Theory" by Sze Kui Ng (arXiv:math/0004151v3). Our Mr Ng has been working on this since about 2000, during which time a lot of progress has been made in understanding knot invariants. Now and again big-name physicists follow Kelvin's precedent and take another look at knots. The latest is Ed Witten, so maybe we should sit up and listen?
