Effective Theory Predictions for LHC Processes

Monday, 25th October, 12:00hs - IFAE Seminar room.

Speaker: Christian Bauer  (LBNL, Berkely)


This talk will give an introduction to effective field theories and how they can improve our theoretical understanding of collider physics. After discussing the basic ideas of effective theories, I will present briefly a relatively new effective theory called SCET which is suitable for collider physics. I will then

Yang-Mills theory in 2+1 dim. (Schrödinger wave functional and Hamiltonian treatment by Karabali, Kim and Nair)"

Wednesday October 20th, 14:00hs - Multifunctional room

Speaker: Sebastian Krug


We review the treatment of 3 dimensional Yang-Mills theory in the fieldtheoretical Schrödinger picture done by Karabali, Kim and Nair, which gives an analytical continuum calculation of the vacuum wave functional, string tension, gluelump spectrum, etc. starting from first principles. For a review paper see hep-th/0309061.

Universal Extra Dimensions on (Projective) Sphere

Friday October 8th, 14:30hs - Seminar room

Speaker: Kin-ya Oda (Osaka University)


We propose a six dimensional Universal Extra Dimensions (UED) model compactified on a real projective plane $RP^2$, a two-sphere with its antipodal points being identified. We utilize the Randjbar-Daemi-Salam-Strathdee spontaneous sphere compactification with a monopole configuration of an extra

Sommerfeld Effect in Dark Matter

Wednesday October 6th,14:00hs -  Multifunctional room

Speaker: Pr. Subhendra Mohanty


Observations of positrons in Pamela experiment demand that DM cross section is 10^3 - 10^4 times larger than what is expected from relic density calculation. I show that the Sommerfeld effect changes the relic density calculation and also the annihilation cross section in the present universe so that one can explain PAmela observations




Precision Gauge Unification from Extra Yukawa Couplings

Friday October 1st, 14:30 hs -  Seminar room

Speaker: Arthur Hebecker (University of Heidelber)


Extra vector-like GUT multiplets can have a significant impact on the predicted value of the strong coupling. In particular, Yukawa couplings between such extra multiplets and the MSSM Higgs doublets can resolve the familiar two-loop discrepancy between the SUSY GUT prediction and the measured

Minimal Conformal Technicolor and Precision Electroweak Tests

Tuesday September 21st, 14:30hs - Seminar room

Speaker: Ruggero Tacchi (University of California, Davis)



I will talk about the minimal model of conformal technicolor and how the electroweak symmetry breaking is delivered in this theory. The chiral symmetry breaking follows the pattern SU(4) --> Sp(4) and generates two uneaten pseudo-Nambu-Golstone bosons: a composite Higgs and an additional neutral

Low Scale Flavor Gauge Symmetrie

Friday September 17th, 14:00hs - Seminar Room

Speaker: Giovanni Villadoro (CERN, Geneva)



I will discuss the possibility of gauging the Standard Model flavor group. Anomaly cancellation leads to the addition of fermions whose mass is inversely proportional to the known fermion masses. In this case all flavor violating effects come out to be controlled roughly by the Standard Model Yukawa, suppressing transitions for the light generations. Due to the inverted hierarchy the scale of new gauge flavor bosons could be as low as the electroweak scale without violating any existing bound but accessible at Tevatron and LHC. The mechanism of flavor protection potentially provides an alternative to Minimal Flavor Violation, with flavor violating effects suppressed by hierarchy of scales rather than couplings.
