It is a pleasure to publish the first issue of PTEP (Progress of Theoretical and Experimental Physics) with special feature articles. PTEP is an open access, online-only journal that covers the fields of particle physics, nuclear physics, astrophysics, cosmology and related areas. As its predecessor, PTP (Progress of Theoretical Physics), which was established by Dr H. Yukawa in 1946, has focused mainly on the theoretical aspects of these fields, a journal to cover experimental research has been on the waiting list for a long time. Considering the rapid progress in the fields, one could argue it has come too late. It is still a quantum leap to launch a new scientific journal in a new media form which aims to be a major information center at the forefront of its research fields.
In order to establish PTEP as a major journal, we need to make it attractive so that you, the readers of this article, are eager to choose it as your main journal to publish your own research accomplishments. While PTEP may expect to inherit the long tradition of its highly esteemed predecessor PTP in the field of theoretical physics, it is a newcomer in the field of experimental physics. These special feature articles are being published to fill the gap prior to the appearance of regular issues which start from the beginning of 2013. Our intention is to familiarize you with the journal, introduce you its aims and scope and encourage you to submit your papers for publication.
For these reasons, we have chosen topics mainly in the area of experimental physics, starting with ‘Computational approaches in Particle, Nuclear and Astrophysics’ in this issue. Others will follow including:
‘Particle and Nuclear Physics at J-PARC (Japan Proton Accelerator Research Complex)’
‘Researches in RI Beam Factory at RIKEN Institute’
‘High-Energy Accelerator Physics’
These issues will be published up to the end of this year. They consist of invited papers only and authors have been chosen from active core researchers in the fields. They are organized in such a way that they may serve as the most recent reviews on the fields in general and also as introductions to those who currently work outside these subject areas. In addition, they may also serve as useful and practical manuals for users of the above accelerator facilities. If you read through all of them, you can gain a good perspective of the fields as they stand now. We hope that you will see fit to keep them at your side for a long time to come and encourage you to submit your forthcoming papers to PTEP on a regular basis.
With best regards,
