دانلود کتاب Origin of Mass and Strong Coupling Gauge Theories: Proceedings of the Sakata Memorial KMI Workshop, March 2015

This volume contains contributions to the workshop, which was largely focused on the strong coupling gauge theories in search for theories beyond the standard model, particularly, the LHC experiments and lattice studies of conformal fixed point. The main topics include walking technicolor and the role of conformality in view of the 125 GeV Higgs as a light composite Higgs (technidilaton, and other composite Higgs, etc.). Nonperturbative studies like lattice simulations and stringy/holographic approaches are extensively discussed in close relation to the phenomenological studies. After the discovery of 125 GeV Higgs at LHC, the central issue of particle physics is now to reveal the dynamical origin of the Higgs itself. One of the possibilities would be the composite Higgs based on the strong coupling gauge theory in the TeV region, such as the technidilaton predicted in walking technicolor with infrared conformality. The volume contains, among others, many of the latest important reports on walking technicolor and related subjects in the general context of conformality, in a way of direct relevance to the LHC phenomenology as well as the lattice studies. It is very timely to study full theoretical implications in the exciting era when the LHC is vigorously working. This volume is of great importance for that purpose. Speakers of 40 talks (plus posters) include K-I Aoki, Y Aoki, K Bamba, E Bennett, R S Chivukula, H Georgi, A Hasenfratz, D-K Hong, K Itoh, D Elander, G Fleming, H Fukano, Y Iwasaki, M Jarvinen, D Kadoh, S Kim, R Kitano, K-I Kondo, J Kuti, D Lin, N Maru, H Matsufuru, S Matsuzaki, K-I Nagai, C Nonaka, H Ohki, E Pallante, M Rho, E Rinaldi, F Sannino, D Schaich, A Shibata, R E Shrock, E H Simmons, K Tuominen, C H Wong, N Yamada, M J S Yang, and K Yamawaki. Readership: Graduate students, researchers and professionals in the fields of particle theory, particle experiment and astrophysics/cosmology.

Nagoya SCGT workshop has a long history, starting back in 1988: \New Trends in
Strong Coupling Gauge Theories (SCGT 88)". The SCGT 88 was largely focusing
on a couple of our new proposals in mid 80's: The \Hidden Local Symmetries"
formulating massive composite vector bosons as gauge bosons, and the \Walking
Technicolor" which, having a large anomalous dimension near unity, predicted a
\Technidilaton" as a light composite Higgs. The latter model was based on the
scale-invariant/conformal strong gauge dynamics, with the coupling being almost
constant near criticality on the xed point. Following the line we propose yet
another model \Top Quark Condensate", a composite Higgs model having even
larger anomalous dimension, which was a main topic together with the above two
at the second meeting SCGT 90 in 1990.
The Nagoya SCGT series then continued in 1996, 2002, 2006, 2009, 2012
(SCGT12Mini and SCGT12), 2014 (SCGT14Mini and SCGT14) and the present
one, SCGT15, all discussing the development of the relevant new strong gauge
dynamics. For some information on these workshops see http://www.kmi.nagoyau.

In March 3-6, 2015, we organized the \Sakata Memorial KMI Workshop on
Origin of Mass and Strong Coupling Gauge Theories (SCGT15)" at the Sakata-
Hirata Hall of Nagoya University. Shoichi Sakata at Nagoya University proposed in
1956 the Sakata model, a composite model for hadrons, which paved a way to the
quark model and eventually to the Standard Model today. We are inspired by his
never-ending enthusiasm seeking the deeper level of matter.
Following the tradition of previous SCGT workshops, the purpose of the
SCGT15 was to discuss theoretical and phenomenological issues of strong coupling
gauge theories, particularly in view of the new phase of the LHC experiments and
the conformal xed point for the gauge/gravity. Synergy of the lattice, string and
phenomenological studies at the meeting was extremely important in this phase of
the particle physics.
During the 4-day sessions we had 85 participants (21 from abroad), with 39
talks in the main program and 23 talks at poster sessions. Topics were broad,
not just conformal strong gauge dynamics but various aspects of strong coupling
gauge theories, in a wide variety of approaches covering lattice studies, holography,
Schwinger-Dyson/Bethe-Salpeter equation, eective theories, and so on. We do
believe that the presentations included in the Proceedings are very useful for those
who are interested in the strong coupling gauge theories in the revolutionary era of
LHC.
