QCD IN BEAUTY DECAYS: SUCCESSES AND PUZZLES Talk at XXXIXth Rencontres de Moriond: QCD and Hadronic Interactions
ثبت نشده
چکیده
The status of the heavy quark expansion for inclusive B decays is briefly reviewed from the perspective of confronting theory with data and of extracting the heavy quark parameters. A good agreement between properly applied theory and new precision data is observed. Some recent applications to the exclusive heavy flavor transitions are addressed. I recall the ‘ 1 2 > 3 2 ’ paradox for the transitions into the charm P -wave states. Bicocca-FT-04-6 UND-HEP-04-BIG04

Four Small Puzzles That Rosetta Doesn't Solve
A complete macromolecule modeling package must be able to solve the simplest structure prediction problems. Despite recent successes in high resolution structure modeling and design, the Rosetta software suite fares poorly on small protein and RNA puzzles, some as small as four residues. To illustrate these problems, this manuscript presents Rosetta results for four well-defined test cases: the...
متن کاملQuantum Theory: Exact or Approximate?
Quantum mechanics has enjoyed a multitude of successes since its formulation in the early twentieth century. It has explained the structure and interactions of atoms, nuclei, and subnuclear particles, and has given rise to revolutionary new technologies. At the same time, it has generated puzzles that persist to this day. These puzzles are largely connected with the role that measurements play ...
متن کاملParticle Physics—future Directions
Wonderful opportunities await particle physics over the next decade, with the coming of the Large Hadron Collider at CERN to explore the 1-TeV scale (extending efforts at LEP and the Tevatron to unravel the nature of electroweak symmetry breaking) and many initiatives to develop our understanding of the problem of identity: what makes a neutrino a neutrino and a top quark a top quark. Here I ha...

You might know the address of IJPR editorial office; it's in Vali-e-Asr Street just about two kilometers from Vanak square. Vali-e-Asr is one of the longest main streets in Tehran. Tehran is one of the biggest capitals in the world with a population of more than 14 million. The earth is home to more than six billion human beings with huge diverse ethnic backgrounds. Starting from the IJPR offic...
