Scientists have recently made significant progress in the challenging task of measuring the mass of neutrinos, often referred to as "ghost particles." This achievement has the potential to disrupt the widely accepted Standard Model of particle physics.
Neutrinos, with their lack of electrical charge and almost negligible mass, pose a unique challenge to researchers. They move through regular matter at speeds close to that of light, making them extremely difficult to detect and measure accurately.
Unprecedented Sensitivity in Measurement
In a groundbreaking study published in Nature Physics, researchers have pushed the boundaries of precision in measuring the upper limit of the neutrino's mass. The experiment required sensitivity so high that it could detect a single drop of water on an Airbus A-380 at maximum load.
Neutrinos, which permeate our universe, are constantly passing through our bodies at a rate of about 100 billion per second. These elusive particles are produced in various cosmic phenomena, from stellar nuclear fusion to particle accelerators on Earth.
Previously, scientists believed that neutrinos had no rest mass, aligning with the principles of the Standard Model. However, the discovery of neutrinos emanating from the sun challenged this assumption, leading to the realization that neutrinos can change between different "flavors," indicating a non-zero mass.
The Intricacies of Neutrino Mass Measurement
Due to the quantum mechanical mixing among different neutrino flavors, their mass is not well-defined. Physicists focus on determining the upper limit of the neutrino's mass rather than an exact value. The intrinsic mass of neutrinos contributes to only a small fraction of their total mass, with the majority coming from binding energy within atoms.

One of the most precise measurements of neutrino mass was achieved by the Karlsruhe Tritium Neutrino experiment (KATRIN) in Germany. By studying the energy released during the decay of superheavy hydrogen, researchers estimated an upper limit of 0.8 electronvolts for the neutrino's mass.
Another method involves observing the capture of an electron by holmium-163, resulting in the release of a neutrino. By comparing different measurement techniques, scientists aim to refine their understanding of neutrino mass and identify potential sources of error.
Advancements in Neutrino Mass Measurement
To enhance the precision of neutrino mass measurements, researchers developed the Penantrap experiment, utilizing a combination of Penning traps to capture and analyze charged ions. This innovative approach has led to a 50-fold increase in measurement accuracy compared to previous experiments.
With each new discovery and advancement in neutrino research, scientists move closer to unraveling the mysteries surrounding these ghostly particles and their fundamental role in shaping the universe.
Travis Japan’s New Song “Sweetest Tune” Featured in TV Asahi’s Drama “Tokyo Tower” Starring Ren Nagase
Travis Japan’s new song “Sweetest Tune” (pronunciation: Sweetest Tune) will be featured on TV Asahi’s Osidora Saturday “Tokyo Tower” starting on the 20th (every Saturday from 11:00), with King & Prince’s Ren Nagase star that the embedded song. The announcement was made on the 19th during an Instagram live held to commemorate Genta Matsuda’s birthday.
“Tokyo Tower” starring Ren Nagase
This work is based on the novel of the same name by Kaori Ekuni published in 2001. The story depicts the beautiful but unforgivable love between Toru Kojima (Nagase), a 21-year-old medical student, and Shishi Asano (Yuka Itaya), a married woman who is over 20 years older than him. In 2005, it was made into a film starring Hitomi Kuroki and Junichi Okada, and in 2014, it was made into a TV drama in South Korea.
This work is a work that boldly depicts the beautiful but unforgiving love between Tooru and Shishi, and their agile and sweet world, with a story and characters unique to Reiwa’s new era, set in the hottest spots in modern Tokyo. Along with Tooru and Shishi, the film also depicts the dangerous relationship between Koji Ohara, a college student played by Matsuda, and Kimiko Kawano, a lonely housewife played by MEGUMI. The legendary romance novel “Tokyo Tower” has become a hot topic as it has been turned into a serial drama for the first time in Japan.
