Martin C. E. Huber,
Herwig Shopper,
David George Walmsley,
Dennis Weaire (Coordinator)
“This large unit has produced some truly remarkable achievements and some of its groups are at the leading edge of European Physics Research, acting on and contributing to hot current issues. About half of the members are working in elementary particle physics.”
...
“All the topics under investigation are of great relevance and on the cutting edge of particle theory, e.g. SUSY and CP violation, neutrino masses and neutrino mixing, baryogenisis through leptogenisis. Topics that combine particle and astrophysics concern dark matter, dark energy and inflation. But also data from B-factories are analysed.”

9. International Networks
CFTP Participates in three EUROPEAN NETWORKS, which include some of the most prestigious Universities and Research Institutes in Europe.
The competition among the various Universities/Research Institutes is very strong, so the fact that we are part of 3 NETWORKS, reflects the recognition of CFTP in the international context as a center of excelence
and the leader Theoretical Particle Physics in Portugal.
NETWORKS:
Tools and Precision Calculations for Physics Discoveries at Colliders
(17 institutions including the universities of Durham, Paris Sud, INFN, DESY, Max-Planck-Institut,
Brookhaven National Lab, KEK, CERN)
Quest for Unification
(13 institutions, including Saclay, INFN, Oxford U., Valencia U., CERN and Stanford U.)
EtaMesonNet, in the context of HPI3 Hadron Physics Integrated
Infra-structure Initiative) of the VI Framework Project
(31 institutions, including London U.C., Hamburg U., Helsinki HIP, Uppsala U., Valência U., INFN)

10. Important International Working Groups
We have also collaborated in several International Working Groups contributing to the preparation of the final reports:
The CERN Workshop "Flavour in Era of LHC" in the subgroups:
WG1: "Collider aspects of flavour physics at high Q",
WG3: "Flavour in the lepton sector, EDMs, g-2, CP violation"
"European Network of Astroparticle Physics" (ENTApP) in the subgoup:
WG1 "Double Beta Decay and related topics“

11. CFTP PASC Cooperation with National Research Institutes LIP CENTRA
CFTP, LIP (particle phys. experimentalists) and CENTRA (astrophysics),
have joined efforts and created the PASC initiative.
We want to increase the offer of courses and post-graduate studies of
Physics Engineering in Particle, Astrophysics and Cosmology, at the level of Master of Science (2nd Bologna cycle) and Ph.D. (3rd Bolongna cycle).
PASC is going to intensify the interaction of the 3 centers.
PASC has about one 100 researchers with PhD.
The 3 centers maintain also intense international collaboration with the world's leading scientific institutions in these areas, such as CERN and ESO as well as with a great number of European, American and Japanese universities, participating also in important Networks
financed by the European Union.

12. Successes of PhD students and Post Docs
CFTP program for training Ph.D Students and Post-Docs
CFTP has given special importance to the training of Ph.D graduate Students and Post-Docs.
Perhaps the most objective way of judging the quality of a program of training Ph.D Students and Post-Docs is by investigating their carreers after they leave CFTP.
CFTP is proud that our Ph.D students and Post-Docs have done very well after leaving CFTP.

16. Research in Particle Physics
Anticipating a New Golden Age
Frank Wilczek (Nobel Laureate, MIT)
“The Standard Model of Fundamental Interactions is
remarkably successful, but it leaves an unfinished agenda.”
“Several major questions seem ripe for exploration in the
near future.”
“I anticipate that the coming decade will be a golden age of
discovery in Fundamental Physics.”
Theoretical Physics in Portugal 2008

17. Some of the Fundamental open questions
in Particle Physics
What is the origin of Electroweak Symmetry breaking?
How to understand the origin of Mass and the pattern of Fermion Masses and Mixings, including Neutrinos?
Supersymmetry: if present at what scale will it be manifest?
How to generate the observed Baryon Asymmetry of the Universe?
How to solve QCD?
What is Dark Matter?
What is Dark Energy?
Quantum Gravity: an old fundamental question.
Are there Extra Dimensions?
What else is out there?
Theoretical Physics in Portugal 2008

18. Research work of CFTP Most plausible answer:
The work of CFTP covers most of the 10 questions listed by Frank Wilczek.
Question 1: What is the origin of Electroweak Symmetry breaking?

19. The work of CFTP covers most of the 10 questions listed by Frank Wilczek.
Question 2: How to understand the origin of Mass and the pattern of Fermion Masses and Mixings, including Neutrinos?
This is one of the most fundamental questions in Particle Physics which has become even more intricate since the discovery of Neutrino masses and mixings.
Main point: Gauge invariance does not constrain the flavour structure of Yukawa interactions. As a result, most of the free parameteres of the SM consist of fermion masses and mixing.

Counting of parameters:
Quark sector:
6 quark masses + 3 mixing angles + 1 cp violating phase= 10
Lepton sector:
6 charged lepton masses + 3 mixing angles + 3 cp violating phases = 12
So altogether we have 22 free parameters in the fermion sector!!!
There has been in CFTP a lot of work on this question using the introduction of Family symmetries and/or the use of Weak-Basis invariants. Some of this work has had a great impact in the literature (see the list of CFTP papers with 100 or more citations)
Theoretical Physics in Portugal 2008

20. Supersymmetry, if present at what scale will it be manifest?
Question 3 (and 8):
Supersymmetry, if present at what scale will it be manifest?
Although there is not yet direct experimental evidence for
SUSY, there are many theoretical arguments indicating that SUSY
might be of relevance for physics below the 1 TeV scale.
The most commonly invoked theoretical arguments for SUSY are:
Interrelates matter fields (leptons and quarks) with force fields (gauge
and/or Higgs bosons).
As local SUSY implies gravity (supergravity) it could provide a way to
unify gravity with the other interactions.
As SUSY and supergravity have fewer divergences than conventional field
theories, the hope is that it could provide a consistent (finite) quantum
gravity theory.
SUSY can help to understand the mass problem, in particular solve the
naturalness problem (and in some models even the hierarchy problem) if
SUSY particles have masses ≤ O(1TeV).
Unification of Gauge Coupling better in SUSY GUT’s.

21. The work of CFTP covers most of the 10 questions listed by Frank Wilczek.
Question 4: How to generate the observed Baryon Asymmetry of the Universe?
We have addressed this question in the framework of
Baryogenesis through Leptogenesis, where first a Lepton Asymmetry is created
through the CP violating decays of the Heavy Neutrinos and then
this Lepton Asymmetry is converted into a Baryon Asymmetry through
B+L violating but B-L conserving Spharelon processes.
In our work, we paid special attention to the possible connection between
the size of the Lepton Asymmetry generated and low energy parameteres
in the Leptonic sector.

The work of CFTP covers most of the 10 questions listed by Frank Wilczek.
Question 9: Are there Extra Dimensions?
Will we be able to see any signature of Extra Dimensions in the LHC?
And How?
We have addressed this question and constructed models
with Extra Dimensions, where intrinsic geometrical mechanisms
can explain the origin of the large mass hierarchies among the
Standard Model fermions.
