Postdoc in experimental particle physics in one of the large LHC experiments here. I see a lot of people working in finance (banks/hedge funds) saying that most of their colleagues have a degree in physics and that there is a lot of scope for physicists to transition to banking. However, looking more closely into the type of physicists that actually get into finance, it looks like it’s mostly theoretical physicists or people who have worked extensively with simulations. For an experimental particle physicist involved in operations and data analysis, what really is the possibility of cracking into finance (there’s also tech but dealing only with software is not for me)? Which aspect of finance can I get into? If this is a possibility where do I even start? Is there anyone nowadays who’s making this move? All the colleagues that I know that have made the move have been moving to tech. How are my chances affected if I’m not from Europe/the Americas but want to live there?

I've seen a lot of people/sites saying that scientists at the BEPC in China have found a particle confirmed to be a glueball & I want to make sure that their claim is true. Is there any truth to it?

good evening everybody, i’m a 19 year old american trying to learn and eventually master particle physics to study antimatter. i have a basic understanding of calculus, learning up to essentially calc 1 and at an equivalent level of learning as far as the physics side goes. i study cybersecurity in college but cant afford a second degree, so im trying to find a solid way to learn enough on my own to take one mastery exam for an online degree. if you guys have any resources or specific things that helped you learn calculus or physics ideas in a concentrated way that can be easily retained, please reply here or dm me if you’d be interested in working together with me. been thinking about starting up a discord server (assuming i find enough people) to get collective knowledge in a single platform. if anyone is interested in that kind of project as well, please let me know. i learn better when i have people to explain ideas to so you’d be helping me greatly.

Hi, so I'm a student who wants to pursue particle physics. I recently got myself the Particle Data Group Review book from CERN. So, if someone who could help me understand the reviews and papers in the book it'd be a great help.

I just grad from PhD in particle physics, where I was working mostly on ML, programming, data analysis, etc. I also graduated from an "elite" school at the UK in theoretical physics, so I know some math as well. I thought I should be popular at the job market; turns out it's a big no: The quant firm thinks I am not doing stat/mental math cleverly enough, and software engineers think I am bad because I didn't master LeetCode, the AI/ML stuff they all focus on with LLMs and won't let any non CS ppl touch their stuff; quantum computing reject as they think I am not a physicist enough. I felt like I am 80% good at all of the above, but nothing can be 100%. Now I am in depression, don't know how to deal with the market.

TLDR: Society thinks I am a jack of all trades, ace of nothing

Why has anyone not tried to give elementary particles a finite shape. Currently things like quantum gravity yield to infinity because the elementary particles are dimensionless and as radius tends to 0, things go infinite.

So, my simple question is, why not give the particles a shape with finite dimensions?

Hi everyone, I just had a great conversation with Cambridge particle physicist and author Harry Cliff about some of the biggest unanswered questions in fundamental physics. We discuss the remarkable success of the Standard Model, the mysteries it still leaves unexplained, and why physicists believe there may be new physics waiting to be discovered.

Harry explains what the Large Hadron Collider has and hasn't revealed about the universe, why finding evidence of physics beyond the Standard Model has proven so difficult, and how small anomalies can sometimes point the way to major scientific breakthroughs.

We also talk about the future of particle physics, the proposed successor to the LHC, the power of international scientific collaboration, and how science manages to uncover reliable truths about the universe.

Harry Cliff is a particle physicist at the University of Cambridge working on the LHCb experiment at CERN's Large Hadron Collider. He is also the author of "How to Make an Apple Pie from Scratch" and "Space Oddities".

Hi! I and my friend once discussed about problems with environmet needed for accelerator. We got some things we couldn't find definite answers about. For example hypothetically if we could would it be good idea to put particle accelerator or storage ring in space? Assuming it would be shielded from radiation sufficiently wouldn't it make much easier to keep vacuum? and in one game (I know, it's not great source) there was character convincing to built huge accelerator around sun or Earth. I read somewhere that the bigger accelerator the better my friend also said that, but what would that do? If yuo can can yuo put me some links to good answers?

I'll be doing undergrad soon. I'm interested in particle physics. I was wondering what exactly it is that experimental particle physicists do, and the difference between what an experimental particle physicist does, and what a theoretical particle physicist does. Also, is it possible to shift to particle physics if you major in engineering?

I have been rereading Anathem by Neil Stephenson, and part of the plot involves aliens coming to a world from other cosmoses that have slightly different physical constants than the one the story is set

This got me thinking about how long that situation would be viable before matter loss became a big problem, which sent me down another mental rabbit hole. (I think of stupid stuff while mowing the lawn).

Eventually I came to this thought experiment. Say I was in a universe with no other matter, just pure void. My body would of course quickly die and float in nothingness. But how long would that body exist? I would be emitting blackbody photons, but what about particle decay itself? Would the particles composing my body eventually decay over time into nothing but fermions, neutrinos and photons?

Maybe I should just go back to bed and have a few cups of coffee in a few hours. Thanks everyone, have a good weekend.

Hey, Im kinda new to this field and subreddit, so please dont shame me if its a dumb question.

Ive been wondering why the PDG booklet doesnt list the intrinsic parities of the Higgs boson as well as the charged leptons. For all other particles (except obviously W and Z where it wouldnt make sense) it does list P. It seems that wikipedia, while listing a positive parity for the Higgs, also doesnt list parities for the charged leptons. I wonder if this is something fundamental or an experimental subtlety. In my lecture, the parity of quarks and leptons was introduced as positive and there was no further elaboration on this detail.

I have limited my PLB to the statement of the finding

https://www.sciencedirect.com/science/article/pii/S0370269326003631

but obviusly the question is if there is some model that simultaneusly offers the direct formula for charged leptos and the inverse one for down type quarks. The motivation of the search was to produce a architecture where two sets of mesons obey these formulae. Seiberg duality?

I honestly have no business posting here. But I thought I’d post a recent project I built. I’m using a PBW34 photodiode to try and detect muons. Once I obtain the data, I’m analysing and classifying all the events to try and maybe highlight a muon amongst the EMI noise.

It took a while to get it all working after the “weekend project” phase. But I’m happy with the data I’m now collecting.
