First talks direct maintain been given at ICHEP 2016 inward Chicago, the primary annual particle physics conference, together with 1 of the experimental collaborations at the LHC is using this chance to print lots of physicists amongst their novel results.
Very quickly, the CMS Collaboration has released 22 novel papers. (A message from the future: Influenza A virus subtype H5N1 few hours later, sixteen were added; I analyzed those after together with added some novel discrepancies. The same applies to 15=14+1 additional papers a few to a greater extent than hours later.) I really had to learn to the 2nd together with 3rd page (with 10 papers per page) – which don't display the appointment equally clearly equally the begin page – to learn all the novel papers. That's unusual.
The 3rd term, 1, inward the release 22+16+1+15 inward the title, is the new CMS diphoton newspaper killing the \(750\GeV\) cernette. Nothing is in that place at all. Totally inconclusive excesses emerged at \(620\GeV\), \(900\GeV\), together with \(1300\GeV\) where a slight excess was seen past times CMS inward 2015, too, but zilch was in that place inward ATLAS. (LOL, they after removed the novel newspaper except for pages 1,2 but besides bad, I already saw it, together with you lot tin flame see the fundamental graph, too.)I won't pretend that I direct maintain read every alphabetic lineament inward these 22 papers. My belief is that the release of people inward the Blue Planet exterior ATLAS, CMS who really read all these papers is smaller than 10 together with fifty-fifty inside the LHC collaborations, the numbers could live really low. But I tin flame offering you lot the next minimum of the analysis:
I really recommend to ship your almost finished pheno papers on the \(750\GeV\) bump to vixra.org (a bluish submit push is at the top) then that those amateur scientists direct maintain some contest together with motivation.
- I watch at to the lowest degree 80% of the expanse of every page of every novel ATLAS/CMS newspaper for at to the lowest degree 0.2 seconds
- I pass at to the lowest degree 3 seconds past times looking at every Brazilian nautical chart inward every paper
- Every newspaper is searched for the words "excess", "deviation[s]", together with "*agree*" together with I am looking for anomalous sentences amongst these words (to increment our combined sensitivity, you lot shouldn't purpose just the same algorithm)
- Reading whole paragraphs or pages is optional
What direct maintain I seen? Well, the begin hitting characteristic of this novel bunch of papers is that nosotros may endure read some of the papers that are based on the 2016 \(\sqrt{s}=13\TeV\) information – which were taken at most 2 months agone or so. The unloosen energy is the same equally inward 2015 then they belike know how to analyze the information together with write papers quickly.
The relevant part of the information taken past times CMS inward 2016 is commonly given past times 12.9 inverse femtobarns of data. Note that this whole 12.9 was taken inward the begin one-half of 2016. They never combine the 2015 together with 2016 data. They could combine them together with increment 12.9 past times something similar 2.7 that is used inward many CMS papers based on the 2015 data.
Similarly, ATLAS began to exhibit its results based on 13.3/fb of the 2016 information together with e.g. according to
The opening ceremony of the 2016 Olympics inward Rio is tomorrow. Lots of elevation athletes volition live absent (not entirely due to the Zika-carrying mosquitoes from the logo), the games may plough out to live a 2nd course of teaching event.
This understanding betwixt the theory together with the experiment is really impressive together with stunning – peculiarly if you lot compare it amongst the sentiment of a bulk of the people inward the Blue Planet who believe that physics can't peradventure empathize how Nature industrial plant – but nosotros are used to this understanding together with bored past times it (even past times the rediscovery of the Higgs whose bulk seems to live \(124.5\pm 0.5\GeV\) now). Some people fifty-fifty sense nightmares because of it – I don't.
You for sure facial expression me to inform you lot nearly the results that direct maintain raised my eyebrows. Here are the coordinates:
- Higgses \(H\to b\bar b \tau^+\tau^-\) using 12.9/fb, Page 12, Figure 3, some 2.5-sigma local excess for \(m_H\sim 700\GeV\). Some 2-sigma excess close \(m_H\sim 300\GeV\) is belike worth overlooking
- SUSY inward same-sign dileptons, 12.9/fb, Page 14, Figure 6a, some 2.3-sigma local excess for \(H_T\sim 1100\GeV\)
- Resonances inward \(Z\gamma\to\ell^+\ell^-\gamma\), 12.9/fb, Page 6, Figure 3b, some 2-sigma local excess for \(M\sim 375\GeV\). This excess is shaver but CMS yet seems to confirm the excess at \(375\GeV\) from \(2\times 2\) ATLAS, CMS papers I discussed inward March. Note that this novel graph is constructed purely from new, 2016 information – the 2015 information behind my March weblog post service aren't included right away then this may live said to live a genuinely independent confirmation of an older hypothesis (although the weakening of the signal is surprising given the increased luminosity)
- Excited quarks \(q^*\to \gamma+{\rm jet}\), using 2.7/fb from 2015, Page 5, Figure 2, locally a 4-sigma narrow excess for \(M_{\gamma,\rm jet}=2\TeV\), watch also Figure five how it translates to a Brazilian band
- From after 16: A dijet resonance, 12.9/fb, Page 7, Figure 4, 2.6 sigma for \(M\sim 850\GeV\)
- From after 16: Sbottom search inward Higgs-to-diphotons using a razor, 2.3+12.9=15.2/fb (from the twelvemonth 2015+2016=4031 testing if you lot sleep), Page 17, Figure 15, sbottom limits some 2-sigma or \(100\GeV\) lower than expected; watch Smaria's tweet
- From after 16: Multilepton EWK SUSY, 12.9/fb, Page 12, Results, local excesses 1.7 together with 2.5 sigma
- From the bundle of 15: Sbottom search inward jets-met, 12.9/fb, Page 22, Figure 9, locally 3.1-sigma excess, bounds on sbottom bulk past times \(150\GeV\) lower than expected, I verbalise over it below
The past times far largest excess amid these iv anomalies is the 4th one, the \(2\TeV\) excited quarks from the 2015 data. On Page 7, we're told that for the best selection of the parameter \(f=0.1\), the significance of the bump is 3.7 sigma locally together with 2.84 sigma globally. We should facial expression for ATLAS' newspaper on that (is it already out? Update: ATLAS saw zilch close \(2.0\TeV\) inward the photon-jet channel inward 2015) together with for the CMS, ATLAS papers using the 2016 information to watch whether it may live confirmed.
Excesses only about 4 sigma haven't been mutual but we've encountered several of these. We're yet waiting for solid 5-sigma or stronger discoveries of novel physics.
I am perhaps fifty-fifty to a greater extent than intrigued past times the apparent (#3) resonance inward \(M_{Z\gamma\to \mu^+\mu^-\gamma}\sim 375\GeV\) (yes, it seems stronger inward the muon channel now) that has basically appeared inward the 5th paper. Will ATLAS watch an excess over in that place equally well, perhaps a greater one? Update, Sabbatum morning: Nothing, the ATLAS excess over in that place has weakened into 1 of 10 really small-scale upticks, then the \(375\GeV\) storey is belike dead at this point. ATLAS' novel \(Z\gamma\) paper.
Bonus: slides
You may watch a CMS 2016 3.1 sigma locally excess inward an off-Z, sbottom search – facial expression at pages 7, viii inward this presentation or this lady's tweet. The sbottom limits are correspondingly past times \(150\GeV\) lower than expected. It's independent from the (sbottom) anomaly #6 inward the listing inward a higher house together with I after added it equally the entry (paper) #8 inward my list.
Slight sbottom excesses are also seen inward jets+MET but besides small-scale to come inward to my listing above. See also MT2, Page 11, Figure 7c for a slight excess inward "one lite squark" together with three halt 1.9-sigma fully hadronic excesses.
More interestingly, ATLAS after revealed a 3.3-sigma excess inward stops (page 9/36). See also the paper released on August 8th, on Monday.
Matt Buckley believes that some SUSY-like excess is seen inward multijets. It must live a verbalise I haven't seen (?). Or maybe he's intrigued past times Page 19/21 of this talk where the gluino limits are some \(100\GeV\) below the expected ones? But it's belike non besides many sigmas, is it? The newspaper is this one, Figures 9,10, only 1 sigma over there.
