Upgrades in High Energy Physics Experiments

Dear Colleagues,

 The most recent discoveries in high energy physics (HEP), both in the Higgs and in the flavor sector, which reached unprecedented precision, led to a solid confirmation of the standard model (SM) of the particle physics. To broaden our horizons and explore regions where physics beyond the SM could be hidden, all major (HEP) experiments are studying and realizing substantial upgrades to increase their performance and sensitivities. This will, in particular, allow to better understand subatomic particles properties as the spontaneous symmetry breaking and the violation of discrete CP symmetry by the weak interactions. If this technological effort provides new and sophisticated apparatuses, the huge amount of data that will be produced requires the development of complex and elaborate analysis techniques.
This Special Issue collected papers describing several examples of the extensive upgrade program on some of the largest experiments in high energy physics with a particular focus on their expected performance and the benefits for scientific research.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
