Coupling Gravity and the Standard Model: a Conformal Approach
  In 1992 Professor Ryszard R\c{a}czka started to work on formulation of a version of the Standard Model conformally coupled with gravity. Being his student I had got the honour to participate in those researches. The conformally invariant Higgs-Free Model was the result of our investigations. Ryszard R\c{a}czka passed away on 26 August 1996. I present here a short memorial survey of our results.
