Large Hadron Collider - First Step In An Area Unknown To Mankind

In September 2008, the "dreamlike" LHC (Large Hadron Collider) was finally started after a 14-year construction process directed by high energy physicists. Like a science fiction fantasy, researchers re-created a state of the universe 0.000000000001 of a second after the universe was born.

In September 2008, the "dreamlike" LHC (Large Hadron Collider) was finally started after a 14-year construction process directed by high energy physicists. Protons accelerating to 99.9999991% of the speed of light collided in a 27-kilometer circumference tunnel built 100 meters below the surface at CERN (European Organization for Nuclear Research), in the suburbs of Geneva on the border of Switzerland and France. Like an SF fantasy, researchers have re-created a state of the universe 0.000000000001 of a second after the universe was born.

What can we learn from the LHC?

To answer this question, we first must ask ourselves "What is it we don't yet know?" Elementary particle physics studies how to find the root of matter. This understanding is directly linked to the answer to the question of how the university was created. On the surface, there may be the impression that there is no problem that cannot be solved by the Standard Model. In actuality, however, it is merely an effective theory in which the Standard Model has endured through rigorous experimental verifications and in which the behavior of elementary particles have been clearly described. Unfortunately, we are not yet able to clearly answer the simple question, "When and how was the particle mass created?"

To answer to this question, the Standard Model framework calls for the existence of a yet unknown particle called the Higgs particle. Finding this particle is the primary goal of the LHC and is the first step in throwing light on the ultimate answer. If the Standard Model is correct in this energy range, the particle definitely can be found by the LHC. The LHC also has a more profound and intriguing story. For example, it is expected that the supersymmetry particle (SUSY) will be found and new and unprecedented phenomenon related in the extra-dimension will appear. The supersymmetry particle is a candidate for dark matter, which is said to occupy 23% of the universe. The world is watching the LHC.

Going to experimental verification from theory debate

This year's Nobel Prize in Physics went to three Japanese theoretical physicists: Yoichiro Nambu, Hidetoshi Maskawa and Makoto Kobayashi. This is great honor for Japan. Not only has their work contributed to establish a basis for current elementary particle physics but it has also played an important role in defining the direction in which these elementary particle "experiments" go. They have also been rigorously researching ways to prove experimental results. Their work clearly shows that theories and experiments stimulate each other, providing mankind with new insights through a long series of tremendous efforts. For elementary particle physics, however, theories precede experimental verification; countless heated discussions have been held and the experiments on verifying them have not been impossible to be performed. One reason is that the energy that can be generated by an experiment is limited. This is where the LHC comes onstage. As the result of efforts by thousands of engineers and experimental physicists, and international cooperative study, the totally unknown energy range of 14TeV can be experimentally verified. Following that understanding, LHC can be a prologue for elementary particle physics which, in previous times, worked experimentally and theoretically at the same time.

Current and future state

For the first time ever on September 10, protons were successfully circulated in the LHC ring. A helium leakage occurred that was caused by an electrical system failure and the experiment was delayed for two months. This type of problem is not unusual for such a large-scale experiment and is not serious concern. The fact that it was successful to circulating protons in even one direction is proof of the excellence of the technology and the tremendous effort of the engineers and physicists working on the accelerator. There is no doubt that the energy level will reach 14TeV next spring, opening up a new era for particle physics. Frankly speaking, nobody knows what's going to be discovered by the LHC. Regardless of whether there is a new discovery or, nothing is found in our expectations. it is assured that new mysteries will be uncovered, changing the modality of elementary particle physics and influencing not only elementary physics but also adjacent scientific fields. We are on the eve of a revolution.

The Japanese group has made large contributions to the project. Currently, 15 institutions and about 100 researchers from Japan are deeply involved in the project. These institutions include the High Energy Accelerator Research Organization (KEK) and the International Center for Elementary Particle Physics (the University of Tokyo). The contribution of Japan, not just to the LHC but also the ATLAS experimental group (an international research group for the detector installed at the collision point), is tremendous. It is very encouraging to know that Japanese researchers and engineers are assuming leadership not only in theoretical areas but also in experimental areas. The experiment group from Waseda University is also likely to become involved as a member of such a large-scale international experimental project. We must first prove to ourselves that we can contribute to the international community and continued to move ahead by probing intellectual curiosity to search for the truth. The LHC experiment has great possibilities in that it allows us to discover the unexpected and profound physical laws that govern the universe. New discoveries create new mysteries. This profound world is as endless as we human beings with our curiosity and ceaseless efforts.

Transparent electronics devices are present in today’s thin film displays, solar cells, and touchscreens. The future will bring flexible versions of such devices. Their production requires printable materials that are transparent and remain highly conductive even when deformed. Researchers at INM – Leibniz Institute for New Materials have combined a new self-assembling nano ink with an imprint process to create flexible conductive grids with a resolution below one micrometer.

To print the grids, an ink of gold nanowires is applied to a substrate. A structured stamp is pressed on the substrate and forces the ink into a pattern. “The...
