Special Issue Information

Dear Colleagues,

We are happy to announce that the new journal Particles is publishing a Special Issue on “Higgs Physics”, covering recent developments in this area.  

The discovery of the Higgs boson by the ATLAS and CMS collaborations in the year 2012 at the CERN Large Hadron Collider (LHC) was a major breakthrough in particle physics. The discovery of the Higgs boson provides an important step towards our understanding of the electroweak symmetry breaking (EWSB), as well as of the mechanism that generates the masses of the quarks and the leptons, the particles that constitute the ordinary matter in our Universe. This also provides a platform for the search for new physics such as dark matter, supersymmetry, extra dimensions, etc. 

The standard model (SM) of particle physics makes theoretical predictions for the properties of the Higgs boson, and since its discovery the precise measurement of its properties has become an important aspect of particle physics. The most important properties are measurements of its mass, spin, and CP quantum numbers; of its couplings to gauge bosons and to down-type fermions; and of its total decay width, including decays to invisible particles. On the other hand, measurement of the properties of the Higgs boson may also reveal some indirect evidence for the physics beyond the standard model (BSM). Currently, an extensive investigation of its properties is being undertaken by the ATLAS and CMS collaborations at the LHC. So far, no deviations have been observed in the measurements of its properties from the SM predictions. However, there are still some mysteries that remain unexplored in the Higgs sector.

The papers submitted to this Special Issue are expected to reflect original work or to be a balanced review of a field. All submissions will be peer reviewed by internationally recognized experts. This Special Issue will contain an up-to-date coverage of the “Higgs Physics” and its related areas. We expect that the Issue will have a cross-disciplinary nature and will be equally useful for wide audiences such as students, postdoctoral fellows, and senior researchers.

As a Guest Editor, I would like to invite you to submit your unpublished and original research relevant to this topic for publication in this Special Issue of Particles.

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. Particles is an international peer-reviewed open access quarterly 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 1600 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.

The postulate of universal local Weyl scaling (conformal) symmetry modifies both general relativity and the Higgs scalar field model. The conformal Higgs model (CHM) acquires a cosmological effect that fits the observed accelerating Hubble expansion for redshifts z1 (7.33 Gyr) accurately with only one free constant parameter. Conformal gravity (CG) has recently been fitted to anomalous rotation data for 138 galaxies. Conformal theory explains dark energy and does not require dark matter, providing a viable alternative to the standard ΛCDM paradigm. The theory precludes a massive Higgs particle but validates a composite gauge field W2 with mass 125 GeV. Full article

In this paper, we review the status of the computations of the perturbative quantum corrections to the Higgs boson mass in the Standard Model and in its supersymmetric extensions. In particular, supersymmetric theories require a very accurate computation of the Higgs boson mass, which includes corrections even up to the three-loop level, since their predictions are limited by theoretical uncertainties. A discussion about these uncertainties in the context of the Minimal and Next To Minimal Supersymmetric Standard Model is included. Full article
