## Introduction to the Workshop

**John Womersley**
**Fermilab**

## General News

**New Office Building at DØ**
**single story open plan building south of the south parking lot**
**some extra parking will be provided**
**Fermilab is going out for bid in 2 or 3 weeks**
**$200k extra from DOE: size of building 80’ ******** 80’ ******** 80’ ******** 100’ **
**accommodate 65-80 people**
**completion December?**
**we plan to include a new videoconference room to replace the ninth circle (which will be used for offices)**
**Interim space**
**15 seats available at the new muon lab (near SiDet)**
**nice space: a real building with windows, kitchen, etc.**
**any groups interested in moving please volunteer**

## Shifts

**Shift coordinator task split into**
**task identification:  Bill Freeman**
**task assignment: Jae Yu**
**book keeping: TBA**
**Reminder: everyone on the masthead will have to carry out ten shifts before March 1, or show good reason not to**
**shifts elsewhere (SiDet)**
**geography/inability to travel**
**other service work**
- Spokesmen will determine whether this is “good reason”
**Please contact Jae if you would like to get started!**
**There is also a need for 4-6 more silicon shift people**
**contact Phil Gutierrez and/or Cecilia Gerber**

## DOE Lehman Review

**The **_**final**_** Lehman review of the DØ Upgrade was held June 6-7**
**there will be a half-day mini-review in November to close out the project**
**Focused on Silicon, Installation, and Fallbacks/Descoping**
**In general it went OK, though the committee criticized us for our willingness to use schedule contingency rather than descope the silicon detector.  The committee also seemed to be confused about whether we would need to install half of the silicon after March 1. **
**For the record**
**The north half of SMT is due at DAB on November 1, but can still be installed up to January or February 2001.**
**We think it is very unlikely to be delayed more than this, and we are not planning on starting the run with less than the full SMT  **
**We have a set of descoping “trigger” milestones agreed with the lab and we will continue to follow that plan**

## Decision Triggers

## Run I analysis

**84 papers published, 3 accepted, 6 submitted as of 6/17/00**
**No Run I meetings at this workshop**
**(Jianming is organizing a working meeting Wednesday evening)**

## But, we did not come here to watch the corn grow . . .

**WELCOME TO DEKALB, KIDS!**

## The next year

**Commissioning does not stop when collisions begin**
**We need to start to understand how to use the first few months of data taking with the goal of getting the best physics out in due course**
**not (necessarily) the fastest route to slick plots in summer 2001**

## Physics Groups

**Convenors appointed two weeks ago:**
**CKM:**** ****	****	****Rick Jesik and Hal Evans**
**New Phenomena:**** ****	****Sharon Hagopian and Gustaaf Brooijmans**
**QCD:**** ****	****	****Iain Bertram and Marek Zielinski**
**Top/Higgs:**** ****	****Boaz Klima and Meenakshi Narain**
**WZ:**** ****	****	****Armand Zylberstejn and Tom Diehl**
**First meetings of the groups at this workshop ****BUT**
**meetings are in parallel, which makes it hard for people to attend more than one**
**groups **_**must not**_** parcel out all the plum jobs or sexiest analysis topics this week**
**groups must be open, inclusive, and play a coordinating role in physics analysis**

## Physics group marching orders

**The focus during this workshop will be on commissioning, monitoring, calibration, alignment, performance of **
**Detector **
**Online **
**Trigger **
**Offline reconstruction **
**Object id **
**Simulation (fast and slow) **
**Analysis **
**To this end, we would like each physics group this week to pick two well-defined physics topics.  These topics should**
**be accessible with the first 100-200 pb****-1**** of data, and **
**should be chosen to exercise as much of the experiment's infrastructure as possible**.
**Follow the two chosen physics topics from beginning to end, i.e. from detector to ntuples. **

## Examples of questions to be answered

**What ****physics objects**** will be involved in the analysis? **
**Which ****detectors**** can be used to identify these objects? **
**How will these detectors be commissioned? Monitored? Calibrated? Aligned? **
**What are the signal ****triggers****?  Background triggers? Monitor triggers? **
**How will these triggers be commissioned? Monitored? Calibrated? Simulated? **
**What are the rates of these triggers? Rejections? Efficiencies? **
**How will these numbers be predicted?  Measured? **
**How will the ****reconstruction algorithms**** for these objects be optimized? **
**How will the ****tracking / vertexing reconstruction**** be optimized for each of the objects? **
**How will the performance (efficiency, fake rate, resolution) be ****measured****? **
**How will the objects be ****calibrated? Simulated? **
**How will the ****efficiencies and rejections**** of the analysis be measured? **
**How will we perform these analyses in a ****timely manner****? **

## These questions
should be answered during the workshop
in conjunction with the 
ID groups
algorithms groups
detector hardware groups
trigger group, trigger simulation group and triggermeister

The workshop agenda is structured to this end 
use our physics goals to stimulate discussion in all the other meetings
involve people from all subsystems of both hardware and software in the physics

Summarize on Friday

## Run 2b

**DØ sent a document to the PAC (June 5) listing options**
**available on the web**
**Spokesmen met with Mike Witherell (June 8)**
**Run 2b is “the highest priority” (but...)**
**15 ******** 5 fb****-1**
**reaffirmed that a minimal upgrade is desired (cheaper = faster)**
**imagines BTeV run would not start until 2007**
**The next 12 months must also see our plans for Run 2b firmed up and the necessary R&D started **
**Hence meetings at this workshop**
