I am a theoretical physics researcher. I have not published any papers yet, so I do not have that much experience in publishing a paper. Though I am a Ph.D. student, I am also working independently on another topic of interest (physics only) and trying to find out something. This topic is different from my Ph.D. topic, and I am doing this research on my own without anyone's help. I have collected information from google (mostly some websites and from a few research papers), and based on this information, I am trying to do my research. My doubt is - if I didn't get any concrete results, can I still publish my work just as a study? Like publishing some article with the title - "Study of ----"? What if it is just collecting data from different sources and gathering it in one place, what if I didn't find anything new from my data analysis? Can I still publish it?
This seems unlikely if you mean publish with a reputable publisher. The difficulty will be finding someone, other than yourself who will publish it.
You can, of course, publish it yourself on arXiv or similar, though you may need some help from a professor to get an account there. Your university email address may be enough.
But formal publishers are looking for novel results and advances to the state of the art, which you don't seem to have at the moment.
Talk to a professor or to so that you understand the possible consequences of publishing early. On the one hand, your ideas get out there attached to your name. But on the other hand, others are also free to extend your work, even before you do.
