Theory Seminars

Pizza Seminars

Seminar: Composite Higgs vs LHC data

Tuesday April 30th 2013, 2:30pm - Seminar room

Speaker: Andrea Wulzer (INFN Padova)


MAM Seminar : SNc=1,2,3,....infinity! (and tetraquarks)

Wednesday April 17th 2013, 2pm -  Coffee room

Speaker: Santi Peris


After a 5-minute review on the large N expansion of QCD, I'll comment of the recent paper by S. Weinberg (arXiv:1303.0342[hep-ph]) on the use of this expansion for understanding tetraquarks mesons in QCD.


Seminar - Supersoft SUSY at the LHC

Friday April 12, 2:30pm -  Seminar room

Speaker: Adam Martin (CERN)

In this talk I will show how supersoft supersymmetry is super-safe from LHC and flavor constraints

Seminar - Dense quark matter and hedgehog black holes

Wednesday April 10th 2:00pm - Seminar room

Speaker: Prem Kumar (Swansea U)

The properties of quark matter at high density and strong coupling remain largely intractable. The large-N limit and its connection to a holographic string theory dual, may provide a tractable limit of the correponding physics.

MAM Seminar: Polyakov loop, hadron resonance gas model and thermodynamics of QCD.

Wednesday April 6th 2012, 2:00pm -  Coffe room

Speaker: Eugenio Megías (Universitat Autònoma de Barcelona)


The Polyakov loop in the fundamental representation has been used repeatedly as an order parameter in the deconfinement phase transition.

Seminar - Comments on the top quark forward backward asymmetry

Friday March 22th 2013, 2:30pm - Seminar room

Speaker: Michael Trott (CERN)

Abstract: We discuss some aspects of the SM calculation of the top quark forward backward anomaly and some interesting model candidates that are under increasing experimental strain as the LHC program advances.

Seminar: Indirect dark matter searches

Friday March 15th 2013, 2:30pm - Seminar room

Speaker: Francesc Ferrer (Washington University, St. Louis)


Numerous experimental efforts to unveil the fundamental nature of the dark matter are underway, and several tantalizing observations have been linked to its effects in recent years.

Colloquium - Shaping magnetic fields: cloaking, concentration, and transmission of magnetic energy

Monday March 11th 2013, 12:00pm - Seminar room

Speaker: Àlvar Sanchez (UAB)


We show how the application to transformation optics theory to static fields results in new ways of shaping magnetic fields in space.

Seminar - Understanding Heavy Quark-AntiQuark System by Perturbative QCD

Friday March 8th 2013, 2:30pm -  Seminar room

Speaker: Yukinari Sumino (Tohoku U)

Around 1998, due to the discovery of renormalon cancellation, it became possible to describe the nature of a heavy quark-antiquark system (such as bottomonium) based on perturbative QCD, both qualitatively and quantitatively.

Seminar - Surprises of the pQCD application to the low-energy data

Friday March 1st 2013, 2:00pm - Seminar room

Speaker:  D. V. Shirkov (Dubna, JINR)


Small parameter, g<<1, at higher non-linearity usually is treated as perturbation yielding series in its powers. However, neglecting by it changes the type of equation; this yields some surprises. One of them is phenomenon of divergent Asymptotic Series (AS).
