The top quark is very special. It’s the heaviest known elementary particle and therefore strongly interacts with the Higgs boson. The top quark’s interactions with other particles provide promising le...
Heat Load and Stress Studies for an Design of the Photon Collimator for the ILC Positron Source
ILC collimator material stress high power beam absorption heat loads
2012/2/28
The ILC baseline design for the positron source is based on radiation from a helical undulator to produce positrons in a thin target. Since the photon beam created in the helical undulator is circular...

Infrared behavior and gauge artifacts in de Sitter spacetime. I. The photon field
Infrared behavior gauge artifacts
2010/12/27
We study the infrared (long distance) behavior of the free photon field in de Sitter spacetime. Using a two-parameter family of gauge fixing terms, we show that the infrared (IR) behavior of the two-...
We review recent measurements of pure neutral final state production in the two-photon processes, γγ→π0π0 and ηπ0 at the Belle experiment. In the lower invariant mass region, properties of light scala...
Nature of light scalars through photon-photon collisions
linear sigma model light scalar mesons four-quark states two photon production mechanisms
2010/5/7
The surprising thing is that arising almost 50 years ago from the linear sigma model (LSM) with spontaneously broken chiral symmetry, the light scalar meson problem has become central in the nonpertur...

Photon Counting in Astrophotometry. Fundamentals and Some Advices for Beginners
Photon Counting Astrophotometry
2010/4/16
The beginners in astrophotometry are reminded of fundamentals of photon counting. Several advices for new users of electrophotometric technics are given.
Higgs hunting at different colliders is discussed with new possibilities related to photon colliders are discussed. Brief review of discovery potential for new physics is presented.
Last two years were very important in history of a photon colliders. This option is included now in conceptual design reports of the NLC, JLC and TESLA/SBLC projects. All the designs foresee two inter...
