1. The minutes of the thirteenth and fourteenth LHCC meetings (LHCC 94-41 / LHCC 13 and LHCC 94-44 / LHCC 14) were approved without amendment.
2. ATLAS AND CMS REFEREES' REPORTS
The committee heard preliminary reports by the ATLAS and CMS referees. The LHCC notes the substantial progress made by the collaborations as reflected in the technical proposals, and congratulates all those involved for their dedicated efforts.
3. B PHYSICS REFEREES' REPORT
The committee heard a report by the B physics referees, outlining the progress made by the LHC-B collaboration towards a preliminary working design. The LHCC is encouraged by the progress made, and looks forward to receiving a Letter of Intent when outstanding problems have been satisfactorily resolved.
4. WORKSHOP ON FURTHER PHYSICS TOPICS
The session chairmen summarised the main topics covered at the workshop on further physics topics held on 29-30 November 1994. The LHCC noted the interest in diffraction, and expects that such studies may also form part of the LHC experimental programme. The committee encourages interested parties to work together on an integrated approach towards this physics, whilst bearing in mind the LHC physics priorities already established.
5. FUTURE OPERATION OF THE LHCC
The Chairman summarised the progress made in setting up the three expert committees: the LCRB for computing, LDRB for detectors and LERB for electronics. Some details remain to be finalised. Status reports for R&D projects will in future be presented to these committees, whose Chairmen will report to the LHCC. The LHCC will pass its recommendations to the Research Board for approval as before. Proposals for new R&D projects will be submitted to the LHCC, which will refer them to the appropriate expert committee.
6. HEAVY ION PHYSICS
The committee heard a brief status report by the ALICE referees. The LHCC had requested an interim report for consideration at its January 1995 meeting. At the request of the collaboration, the committee agreed that this could now be submitted for consideration at the May 1995 meeting.
7. OTHER BUSINESS
The following referees will make a comparison of ATLAS and CMS physics performance:
L.Di Lella, J.Ellis, P.Igo-Kemenes
It was agreed that the next meeting would be a two-day meeting only, on 30-31 March.
8. DATES FOR 1995 MEETINGS
