Abstract A signcryption, which is an integration of a public key encryption and a digital signature, can provide confidentiality and authenticity simultaneously. Additionally, a signcryption associated with equality test allows a third party (e.g., a cloud server) to check whether or not two ciphertexts are encrypted from the same message without knowing the message. This application plays an important role especially in computing on encrypted data. In this paper, we propose the first lattice-b...

Follow us on FROM TOI PRINT EDITION New particles, new physics: An experiment at Fermilab points to undiscovered forms of matter and energy lurking in the universe April 16, 2021, 7:41 PM IST The author is a science and technology writer. There might be dozens of undiscovered subatomic particles in the universe, and new physics might be lurking around the corner, if the results of a recent scientific experiment, conducted at Fermilab in the US, are corr...

Fundamental particles called muons behave in a way that scientists’ best theory to date, the Standard Model of particle physics, doesn’t predict, researchers report. The finding comes from the first results from the Muon g-2 experiment at the US Department of Energy’s Fermi National Accelerator Laboratory. “This experiment is a bit like a detective story.” This landmark result confirms a discrepancy that has been gnawing at researchers for decades. The strong evidence that muons devi...

A new review published in EPJ H by Clara Matteuzzi, Research Director at the National Institute for Nuclear Physics (INFN) and former tenured professor at the University of Milan, and her colleagues, examines almost three decades of the LHCb experiment - from its conception to operation at the Large Hadron Collider (LHC) - documenting its achievements and future potential. The LCHb experiment was originally conceived to understand the symmetry between matter and antimatter and where this symme...

How a single particle may change everything This week, physicists from the Fermi National Accelerator Laboratory (Fermilab) released a breakthrough publication that may forever change the way we understand the laws of physics. In the publication, the results of Fermilab’s Muon g-2 experiment were

Is there a previously undiscovered fifth force of nature? Scientists in the USA are hoping for a major breakthrough in our understanding of the universe. It all has to do with the behavior of sub-atomic particles called muons. Watch video 02:19

More like this The observer is at rest with respect to the wave source - the waves have speed c relative to him and the frequency he measures is f c/λ. Then the observer starts moving with speed v (v c) towards the source - the speed of the waves relative to him becomes c c+v and the frequency he measures is now f c/λ (c+v)/λ. The relation between c and f is quite natural and it is valid for all waves ... except for light waves. Here a "hierarchy problem" appears. The frequency the moving...
