I am a very beginner and I want to publish my first research in theoretical physics. I do not yet have the terminology of experts in this field. Is it possible to accept a research in physics without high-accuracy scientific terms and experience?
It's very improbable. If you don't know the terminology, odds are you don't know what you're talking about and cannot contribute meaningfully to the field, especially if the field is theoretical physics (this field is complex enough that many physics graduates cannot contribute meaningfully to it).
If I received a paper discussing, e.g., dark matter and it's not clear the author knows what dark matter is, I would probably desk reject.
It is possible, but very unlikely that such a paper would be published. It would be likely to confuse experts if you use terms that aren't standard, though good explanations would help.
More seriously though, is that your lack of knowledge is likely to lead you to write things that experts consider trivial and that you might wind up making erroneous statements.
But, one way to proceed is to find some local source, who is knowledgeable, and ask their advice on what you write.
Your amateur standing is much less important than the accuracy, novelty, and importance of what you write. Occasionally an amateur will have some fresh insight into an important problem, but it is very rare.
Publishing a solo paper is a big ask for someone at the level of "very beginner." Papers take a long time (often at least a month) for experienced people to write well because there are so many layers of details -- ranging from making sure every statement is technically accurate, to making sure there are no ambiguities or ways a sentence can be read in an unintended way, to conventions about hyphenation -- that all have to be checked and double checked.
If you are not sure you have a grasp of the language, my friendly suggestion would be that you are not ready to undertake this. There are other activities you can do. If you have some peer group of people who are at a similar level (if not you should try to form one) you can
- start a journal club where you read papers and explain them to each other
- share your draft with some critical and smart readers and address their comments
- rope one in to collaborate on your paper, have them check calculations and suggest their own ideas
- give a presentation about your work and see if you can explain each step
Even if not, there are many opportunities for self-study
- over the past year there has been an explosion of online conferences with talks available online, find and watch talks relevant for your area
- watch online videos of courses in your field
- take a course in technical writing
- read famous papers in your field carefully
- keep tabs on the arxiv for your field
- prepare slides as if you were going to present your work and give them out loud (I have found talking through every step out loud, even to yourself, to be a surprisingly effective way of finding gaps)
- be skeptical of your own work
