H1 has about 320 authors

38 Institutes from Europe, Asia, America

Inelastic ep Scattering at HERA:

LoI 1985, TP 1986, data since 1992.

investment cost of estimated 80 MEuro

publish 10-15 journal papers a year since 1993

about 60% of the (23) LoI institutes are still on H1

 H1 composition largely changed, though key

institutions are still actively involved.

rules of authorship in H1

you have to visibly do something and be useful for the Collaboration

cover 2(3) items out of hardware, software, shifts

shifts are obligatory - H1 is operated with 2 persons  ~1 shift week/year

authors come from H1 member institutes (very few exceptions for special papers/contributions)

the member institutes shared the construction, upgrades and they share the operation cost (1.4MЄ)

institutes become members by election by the Collaboration board (1 per institute)

most institutes stay for decades, few others go or some new groups join (4 new groups in 03/04)

authors are physicists (PhD students, postdocs, few engineers)

all sign all papers [the question we discuss here]

authorship starts half a year after entry to H1

an authorship ends half a year after someone left (definitely) H1. sabbaticals go unnoticed.

rules of publication in H1

each paper has internally authors and two referee’s from the collaboration. these are known

each paper has an updated authorlist corresponding to the time when a paper was presented to H1

analyses are prepared in working groups. These groups need to agree when a draft goes to H1.

H1 has monthly and weekly plenary meetings which decide on a preliminary release

paper drafts are announced to all of H1 and commented on by a small fraction of the collaboration

the time to comment is 1 week and 2 weekends.

a final public reading is done and papers are submitted afterwards if there are no objections.

[The rules are reproduced here as I recalled them last night. It seemed easier than to find them.]

slide5

How are some obvious problems lived through/solved/tolerated in H1?

  • the hardware-software contradiction
  • the division of labour question
  • the difficulty of young (or old) physicists to become visible to the outside
  • the difficulty to know from outside who has done which work in a collaboration

the experts “in the hall” do not feel alone since they know without them it’s the end

There is no beginning and no end of a paper/analysis. A joint publication implies

that analysis work is ranked equally to detector operation or hardware work etc.

This is necessary and correct, also fair.

Very good, ingenuitive physicists (should) become known via their work and ideas.

A true collaboration tries to help. The ways how to help differ: give someone talks,

give him no talks, give him more work, or time, send him to act as referee, etc.

The evaluation of the quality of a person will always go via his colleagues. Personal

contacts are necessary for real judgement in any case. In an application it

has become standard to separate ‘own’ papers from the ones of the collaboration.

use the telephone to the responsibles. Web is important but less valuable.

The described system

has not been questioned

and was thus stable and

successful over the years.

I personally believe the

problems of adapted

author lists for each paper

likely are significantly

larger, at least for the old

H1 with it’s “only” 300

characters. It would start

with an ‘old men committee’

to decide these problems.

People would fight for their

ranking instead of thinking

and solving real problems.

A large collaboration relies

on a good understanding

in any case. The times of

Geiger, Marsden have passed,

we are now hundreds of people.
