6 questions* defining Particle physics
1. Which are the ultimate matter constituents?2. Which are the forces that bind or break them?3. By which mechanism do constituents get their
masses ? Does the Higgs boson exist?4. What is the nature of neutrinos ?5. Is supersymmetry a valid theory?6. Are there any hints of a GUT theory ?

6 questions* defining Astroparticle physics
1.What is the Universe made of ?2. Do protons have a finite life time ?3.What are the properties of neutrinos ? What is
their role in cosmic evolution ?4.What do neutrinos tell us about the interior of
Sun and Earth, and about Supernova explosions ?5.What is the origin of cosmic rays ? What is the
view of the sky at extreme energies ?6.What is the nature of gravity ? Can we detect
gravitational waves ? What will they tell us about violent cosmic processes ?

Cosmic Rays Spectrum• High energy cosmic rays consist
of protons, nuclei, gammas,…• Measured flux extends to
s1/2 ~ 400 TeV• Highest energy particles are
extremely rare• Supernova shock fronts can
accelerate particles upto 1015 eV• Above ~1015 eV, presumably
acceleration is in AGNs (?)• How do UHECR protons evade
the GZK cut-off at ~7 x 1019 eV(if source is >100Mps away)?
• UHECR manifest themselves as extended air showers (EAS) --an indirect way of measuring CRs

Misteries of the Spectrum• Protons are trapped in our Galaxy (µG B-fields) up to ~1017 - 1018eV• Protons can travel straight above ~1020eV• Supernova shockwave acceleration up to ~1015 eV• Above the knee the acceleration mechanism is essentially unknown:
active galaxies, massive black holes systems, gamma ray bursts ?

Neutrino Oscillations-K2KKEK to SuperKamiokande:
– Confirm the evidence of oscillations observed by Super-Kamiokande– Measure the disappearance of muonic neutrinos in a beam that is
produced in KEK and detected in Super-KamiokandeTwo major contributions:
– Extrapolation of the neutrino flux measured in the near detector to the far detector (from Harp data)
– Contribution to the reconstruction of the new SciBar detector (in collaboration with IFAE)

Conclusions
1. Spain is very active in
Particle & Astroparticle physics and in a continuous growth.
2. We are deeply involved in the CERN program, and more modestly with DESY, Fermilab, SLAC, KEK programs.
3. There are two important infraestructures for Astroparticle Physics: the Canfranc underground lab and El Roque de los Muchachos observatory.
4. My best wishes for a very nice workshop !
