The research performed at the IPhT aims at better understanding the laws which govern our universe and its organisation. It encompasses most of the great subjects of modern theoretical physics:
The IPhT comprises about fifty permanent physicists (2/3 CEA, 1/3 CNRS), about thirty PhD students and postdocs, assisted by a support staff of about ten people. The IPhT also hosts permanently many short term visitors.
It was with great sadness that we learned of the death of Cirano de Dominicis on April 4, 2017, at the age of 90 years. Cirano de Dominicis, a former student of École polytechnique and of Ecole des Mines, spent his entire career at the Atomic Energy Commission, where he participated in the founding of the theoretical physics group at Saclay. An outstanding scientist, his innovative work had profoundly influence on the fields of condensed matter physics, of the Nbody problem, and later on the physics of disordered systems and spi glasses. He was Director of the Saclay theory group (then Service de Physique Théorique) from 1971 to 1979. He has been President of the French Society of Physics, and was the recipient of the Paul Langevin and Ricard Prizes of the French Society of Physics and of the CNRS Silver Medal. He continued his research activities at the Institute and to be involved in scientific life with impressive energy, until ...

The standard model of particle physics arises in string theory from open strings ending on membranes (Dbranes) extended along the threedimensional space. Closed strings propagating along the whole tendimensional world of string theory play the role of the hidden sector, communicating to the matter sector the breaking of supersymmetry that takes place in the extra dimensions in the form of “soft terms” (which have this name because they break supersymmetry without causing ultraviolet divergences).
However, not any softsupersymmetrybreaking Lagrangian can be obtained this way since the string theory equations of motion and consistency conditions impose relations between the soft couplings. Iosif Bena, Mariana Graña and collaborators have shown that for models realized on D3branes the trace of the square of the boson mass matrix is equal to the trace of the square of the fermion mass matrix at tree level, and this equality holds at least up to two loops [1]. String theory thus dictates ...
