3 generation is required for anomaly cancellation, then the 4th generation seems redundant. But there are still papers about the 4th generation, what is the reason?
Thanks
Thanks
That's not quite true.Accidently said:3 generation is required for anomaly cancellation ...
It's allowed theoretically, just as the 2nd and 3rd one.Accidently said:But there are still papers about the 4th generation, what is the reason?
tom.stoer said:I am not absolutely sure but I thought that a 4th generation is almost certainly ruled out experimentally (the 4th generation particles would be too heavy to be produced directly in colliders, they may by too instable to be detected directly, but they do contribute to loops even at lower energies therefore there are indirect indications regarding the number of generations).
The 4th generation models were released in 2010 and were considered groundbreaking at the time. They have since become iconic and still have a large user base, making it difficult for newer generations to completely replace them.
Yes, there have been significant improvements and updates in newer generations such as faster processors, better camera quality, and enhanced features. However, the 4th generation models still have a loyal following and are considered reliable and user-friendly.
Some people may prefer the design or functionality of the 4th generation models. Others may not see a need to upgrade if their current device is still functioning well. Additionally, some users may not be able to afford or justify the cost of upgrading to a newer generation.
As with any technology, the 4th generation models will eventually become obsolete. However, Apple continues to support and provide updates for these models, so they can still be used for several more years. Eventually, newer software and apps may not be compatible with these models, making it necessary to upgrade.
No, there are no specific health risks associated with using older models. However, as with any electronic device, it is important to follow proper safety guidelines and to take breaks from prolonged use to avoid eye strain and other potential issues.
