  Overview of LENT Theory  Low Energy Nuclear Transmutations Yogendra Srivastava Professor of PhysicsINFN & Department of PhysicsUniversity of Perugia, Perugia, Italy CERN Colloquium Thursday March 22, 2012 Geneva, Switzerland yogendra.srivastava@pg.infn.it  LENT I Almost exactly 23 years ago [on March 31 1989],a CERN seminar was organized by Carlo Rubbia,at which Dr. Martin Fleischmann produced evidencefor an anomalously high production of excess heat.The interpretation was that somehow two Deuterons-with very little kinetic energy- could overcome theCoulomb barrier in order to fuse and produce anand aBut textbook quantum mechanics teaches us that theprobability for such fusion to occur for a particle of charge (+Z 1 e) moving with a relative velocity v << c withrespect to another charge (+Z 2 e) is vanishingly small:For thermal deuterons @ 300K: a depressingly smallnumber The Bane of Cold Fusion  LENT II ã Hence, the renewed clarion call for hot fusion -supposedlyoccurring in the core of the stars, for T around 17 Million K ã I say supposedly: for the lack of success achieved so far -after 60 years and over 200 billion dollars- might make you wonder that perhaps a realization of hotfusion on Earth is even more ephemeral than the one at300 degrees. ã While strident criticism of low temperature fusion is legionamong most physicists, the silence generated by the samephysicists regarding hot fusion is positively deafening. ã Europe is spending over a billion Euros on hot fusion this year ã An optimistic estimate for production of usable energy viahot fusion is the year 2025. ã In the US, the prognosis is for the year 2050. ã Curtains for my generation  LENT Theory Giuliano Preparata [Milano][GP was a staff member of the CERNtheory group between 1971-76] These two physicists Giuliano Preparata [Milano] and Allan Widom[Boston] provided fundamental theoretical insights and revolutionizedthe field.Allan Widom [Boston]
