### Workshop

#### Advancing Collider Physics: from Twistors to Monte Carlos

**Aug 27, 2007 - Oct 26, 2007**

**Abstract**

High energy physics is poised to enter a new era of discovery with the start of LHC operations in 2007. The LHC will play a key role in exploring spontaneous symmetry breaking in the Standard Model and in discovering new physics phenomena beyond the Standard Model (BSM). The goal of this Workshop is to develop theoretical tools needed to test the Standard Model with unprecedented accuracy, analyse spontaneous symmetry breaking and uncover evidence for BSM physics at present and future high-energy colliders.Another important aspect of the Workshop will be to support the transfer of knowledge between different communities - new formal developments (like twistors) will be explored and their applications to QCD and electroweak physics will be promoted and studied.

**Topics**

- Higgs Production

- QCD and Higher-order Computations

- Electroweak Physics

- Computer Algebra

- New Formal Developments

Later applications will be also considered

In week 5 of the workshop we shall have a School on LHC physics:

**MonteCarlo (2 hrs) Krauss**

In the first half I will review basic principles of Monte Carlo event generation. In the second half I will concentrate on the inclusion of
higher order corrections into the event generators, and, time permitting, I will briefly discuss the underlying event.

**HO corrections (2 hrs) Campbell **

These lectures will explore the motivation for, and calculation of, higher order corrections in the Standard Model and beyond.
After a review of basic techniques and results, I will discuss some recent state-of-the-art calculations. The lectures will conclude
with a survey of available tools and applications to collider phenomenology.

**Twistors (2 hrs) Roiban **

**BSM (2 hrs) Giudice**

I will review the prospects for the discovery of the electroweak-breaking sector at the LHC and the motivations for searches of
new theories beyond the Standard Model.

**Higgs searches (3 hr) Oleari**

In the first half of the lectures, I will review briefly the basics of the Standard Model and in particular of the electroweak sector. I will
introduce the mechanism of spontaneous symmetry breaking and its consequences.
In the second half, I will review the physics of the Higgs boson at the LHC and its discovery channels.

**Accelerator physics (2 hrs) Scandale**

The main aspects of the particle dynamics in a circular accelerator are reviewed and some of the technological breakthrough recalled.
The LHC project is used as an example to show the up-to-date state of the art.

**Overview of detectors (3 hrs) Dissertori (CMS)**

In these lectures I will give an overview of the design, construction and current status of the LHC detectors, with emphasis on the two
general-purpose experiments ATLAS and CMS. I will illustrate how the experimental challenges at LHC will be met by these large-scale
detector systems.

**DAQ & trigger (2 hrs) Schwick (CMS)**

The lectures introduce state of the art concepts and technologies used in design and implementation of Trigger and Data Aquisistion systems.
The fours LHC experiments Alice Atlas CMS and LHC are analyzed with respect to their requirements. Common system aspects for the four
experiments are worked out as well as the specific solutions to detector specific requirements.
