The Search for New Particles and Forces
In 2010, the Large Hadron Collider (LHC) at the laboratory CERN in Geneva, Switzerland, began its exploration of physics at distances 10,000 smaller than an atomic nucleus. The first data-taking period of the LHC ran from 2010 to 2013, colliding protons at energies of 7 and 8 TeV (trillion electron volts).
Many novel observations were made, including the discovery of the long-sought Higgs boson. However, the most fundamental questions that motivated the LHC remain unanswered. The second data-taking period of the LHC began last summer, at the higher energy of 13 TeV. Results from the first batch of higher-energy data have
already shifted the landscape, with more powerful exclusion of some hypotheses and tantalizing hints supporting others. The results from the next batch of data are highly anticipated; they will be announced in early August. In this talk, I will review the search for new basic interactions in nature and
the experimental methods that the LHC brings to this question. I will describe the implications of the first data at 13 TeV and preview some of the results that might appear later this summer.

|The Search for New Particles and Forces|
|The Forces of Nature
Four fundamental forces rule the universe: gravity, the electromagnetic force and then two that act in and around the atomic nucleus, known as strong and weak.
|We Have a Discovery: The Future of the Higgs Boson
Our panel of experts discussed what the hunt was all about, the importance and broader implications of the discovery, and what we are now planning to do moving forwards.
|The Long Road to the Higgs Boson and Beyond
The discovery of the Higgs boson in 2012 was the end of a decades-long search for a fundamental particle proving how particles gain mass, but its discovery leaves many questions unanswered.
|Expanding Our Horizon: Matter, Space and the Universe
Professor Lisa Randall will tell us about the Higgs boson discovery and its implications. She will also explore possibilities for the nature of dark matter and of space itself.
|Particle Astrophysics at the Large Hadron Collider
Professor Martin White explores the theory of modern particle physics and the search for dark matter.
|The Quandary of the Quark
Professor Christine Davies will describe how the properties of the quark are now being revealed, and the implications that this will have for our understanding of the physics of fundamental particles.
|Particle Physics: Basic Concepts
This course is the first of a three-quarter sequence of classes exploring particle physics. This material focuses on the basic concepts of particle physics.
|Particle Physics: Standard Model
In this series Professor Susskind continues his particle physics theme, focusing on the foundations of the Standard Model, which describes the interactions and properties of the observed particles.
