EPJ Plus Highlight - On the trail of the Higgs Boson

Post-LHC collision showing how the particles decay.

The elusive particle won't share all the secrets of its creation mechanism at once

For the physics community, the discovery of new particles like the Higgs Boson has paved the way for a host of exciting potential experiments. Yet, when it comes to such an elusive particle as the Higgs Boson, it's not easy to unlock the secrets of the mechanism that led to its creation. The experiments designed to detect the Higgs Boson involve colliding particles with sufficiently high energy head-on after accelerating them in the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. In a quest to understand the production mechanisms for the Higgs Boson, Silvia Biondi from the National Institute of Nuclear Physics, Bologna, Italy investigated the traces of a rare process, called ttH, in which the Higgs Boson is produced in association with a pair of elementary particles referred to as top quarks. Her findings can be found in a recent study published in EPJ Plus. Future LHC experiments are expected to yield even more precise measurements of the Higgs Boson's ability to couple with particles that physicists are already familiar with.

Biondi first looked at data from the initial experiments performed in 2010, 2011 and 2012. Unfortunately, that data did not prove to be statistically significant enough to yield a suitable measurement of the processes leading to the Higgs Boson's creation. However, more recent LHC experiments, such as the ATLAS experiment dating back to 2015 and 2016, attained the requisite level of precision to study the ttH creation mechanisms.

In turn, she devised a method for reconstructing the signals that could stem from Higgs particles for each set of collision data. In this way, she enhanced the ability to discriminate between an actual Higgs Boson, background noise, and particles that are in the same energy state, but which do not have the characteristics of the Higgs Boson. She then performed a procedure to compare the expected theoretical measurement of the probability that a Higgs Boson will appear, with the probability of the ttH process taking place.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
