Remarkable Progress in Particle Physics

Over the past ~40 years:


Established that quarks are the fundamental building
blocks of hadrons


Discovery that there are 3 generations of both quarks
and leptons


Established QCD as the theory of strong interactions


Unified Weak and EM interactions


Higgs discovery
is the final piece


Cosmology has become a precise and quantitative
science that is synergistic with particle physics.

The Standard Model is a triumph of the human intellect!

Investments in scientific infrastructure

The huge scientific advance results from brilliance and
hard work of experimenters and theorists, enabled by
investments in major scientific facilities.


Large accelerators and colliders


Large and sophisticated particle detectors


Ground
-

and space
-
based telescopes and cosmic ray
detectors

As well as a host of smaller facilities and experiments

Many big questions remain to be answered


Is there a grand unification of EW and QCD?

If so, at what scale? What “protects” physics at our
scale from the GUT scale?

How can we incorporate gravity?


What is the explanation for the baryon asymmetry of
the Universe?


What is flavor? Why three? Or are there more?


What is dark matter? Is it particles like the ones we
know or something completely new?


What is dark energy?


Why are the Standard Model parameters “just so”?

J.Strait, ASEPS3, 16 July 2013

New investments needed

To address these fundamental questions, we need a
new generation of major facilities.


Higher energy and luminosity lepton and hadron
colliders


More intense and better controlled neutrino beams.


Larger and more capable underground detectors in
larger and deeper underground labs.


Larger and more sophisticated telescopes


Larger and more sophisticated detectors of cosmic
particles (known and unknown)

Planning in a global context

Coordination and cooperation among countries and
regions is increasingly necessary


To pool the required resources


money and people


To ensure balance between maximum investment in
unique facilities and the need for cross
-
checks


To ensure that the broadest spectrum of facilities can
be developed by avoiding unnecessary duplication


We also need to educate the public, who support us, to
help them understand our science and why it is
important to pursue.

National / Regional Planning

Strategic planning processes exist in individual countries
and regions.


Involve input from the scientific community.


Set “domestic” scientific priorities and strategic
directions, considering the world context


Result is recommendations to an entity (a government
or equivalent) which controls resources that can carry
out the plan.


Japan and Europe have recently completed planning
processes.


The US is in the midst of an update, which will be
completed next spring.

The Japanese Plan


Japan should take the leadership role

in
an early realization of an e+e
-


linear
collider
.


continuous studies on new physics

should
be pursued for both LHC and

the
upgraded LHC version
.


Japan
should
aim to realize a large
-
scale neutrino detector
through
international
cooperation,
accompanied
by the
necessary
reinforcement
of accelerator intensity, so
allowing studies on CP
symmetry
through neutrino
oscillations.

J.Strait, ASEPS3, 16 July 2013

The European Plan


Europe’s top priority should be the

exploitation of
the full potential of the

LHC, including
the high
-
luminosity

upgrade
of
the machine
and detectors


CERN should undertake design
studies

for
accelerator projects in
a global
context, with emphasis
on
p
-
p
and
e+e
-

high
-
energy frontier
machines
.


Europe looks forward to a proposal from Japan
[for the
ILC] to
discuss a possible
participation.


CERN should develop a neutrino
programme

to pave the
way for a substantial European role in future long
-
baseline
experiments … in the US and Japan.

J.Strait, ASEPS3, 16 July 2013

The US Plan

Current plan is the 2008 HEPAP P5 report.


Significant US participation in the full

exploitation of the LHC has the highest

priority
in the US
HEP program.


Whatever the technology of a future

lepton
collider, and wherever it is located,

the
US should plan to play a major role
.


The panel recommends a world
-
class neutrino
program
as
a core component of the US program, with the long
-
term
vision of a large detector in the proposed
DUSEL
and a
high
-
intensity neutrino source at Fermilab.


The panel recommends an R&D program
…to
design a
multi
-
megawatt proton source at Fermilab.

Some common themes


Full, worldwide support for LHC and its upgrades.


High priority for developing a high
-
energy lepton
collider. The Japanese community has taken the lead
in recommending to host the ILC in Japan.


High priority for the next generation of long
-
baseline
neutrino experiment(s). The US and Japan both
propose to host it along with the high
-
intensity proton
source that would drive it. Europe willing to help.

Do we have sufficient resources worldwide to do all this
(plus smaller initiatives)?

Can we successfully diagonalize the matrix?

J.Strait, ASEPS3, 16 July 2013

A Worldwide Strategic Planning Process?

Can we expand the national/regional planning processes
to a global scale?


Is there a common HEP community from which to
take input?


How do we involve all countries and regions, not just
those I have discussed


China, India, Russia, other
Asian countries, Latin America,



How
would the plan be carried out? What is the
equivalent of the national governments that receive
the recommendations of the national planning
processes?
