Re: El Reg LHCb story

http://www.theregister.co.uk/2010/04/23/lhc_beauty_antibottom/ :text-yeahthat: :clap: :dance: LHCb is not directly searching for new particles. What it wants to do is to measure rare decays of a b meson. How often these decays occur is predicted by the standard model with rather great precission. I...

Re: 7E10 single injections

Nobody will be looking at filtered-out events later. Thats true, but not as bad as it sounds, because they also later have at least one filterchanel which accepts a small procentage of random collission events only to make sure that the filters not cancel out something unexpected but nevertheless i...

Re: should they have spotted something on the radar by now?

Hi Anitusar ! I think you like LHCb ! I sure do.. Best public live event display.. Hmm, what gave me away :think: Yeah, was kind of cool to make a small contribution to building this detector. Though ATLAS was also pretty impressive just to look at, its really :!: huge :shock: Hi Anitusar ! Im bett...

Re: should they have spotted something on the radar by now?

And.... I am hoping they dont find the Higgs.... :violence-smack: standard model Wouldnt that be just an excuse to do collisions at higher energies? :think: No, if LHC does not find the Higgs, this theory is dead. In fact, the room for this theory in its simplest form is already pretty limited as t...

I should have known you guys would instantly clear up what the issue was...

I was hoping for some really great Ivan comments.

We knew the explanation at about the 4th event in the series in chat, we just figured it would be great entertainment and interesting to Ivan.

Re: Several biggest errors of particle physicists.

A recipe also includes the order of how to setup the electronics. Which is done first and so on, e.g. in which steps the HV is increased or what is turned on when, what has to be on before something else is done and so on.

Re: Several biggest errors of particle physicists.

:icon-idea: A recipe is a certain set of settings for the frontend electronic. A timing recipe is therefore the relative timing adjustments between the electronics within a subdetector and the global detector. :icon-idea:

Re: Several biggest errors of particle physicists.

The flow is

measurements -> track seeds -> tracks (this is what you see in the online displays) -> particles (add particle info) -> decay chains (combine particles)

Re: Several biggest errors of particle physicists.

Hi. Has anyone else noticed that RICH1 and RICH2 are not reporting any hits as they were earlier? I wonder if the lack of information these detectors could be partial to blame for strange results. Allan The Rich1/2 do not play part in the track finding algorithmus, so they can not be the source for...

Re: Several biggest errors of particle physicists.

i think the software may be running as planned. This looks likes a high order regression line drawn through a few data points, with a missing data point near the front end of the detector. i would first look for a hardware failure/error. No, you would not see Hardware failures in these pictures (on...

Re: Several biggest errors of particle physicists.

Yes, its the Software. Remember, all lines in this pictures a reconstructed predictions by the Software. A lot of parameters enter the reconstruction process and sometimes the results go rogue. What actually happened are the measurements presented as x and bars in the calos. From these you try to de...

Re: LHC as detector of relict neutrinos?

No, this will not be possible for several reasons: 1) The problem with Neutrinos is not their low energy, but their very, very, very, very low interaction rate. If you would want to make sure, that a neutrino had an interaction with a material, you would need several lightyears(!) of a gold volume f...

Ah, finally someone explained the obvious things. :D But i did not get, where the catastrophy occurs. We make contact to this 8th dimension and then what? How does humanity get destroyed or enslaved? On a side note: I noticed again that LHCb is not mentioned at all. I feel sad :sad-pacing: Come on ,...

Re: S C I E N C E

I do not see how this should change the argument. The number of cosmic rays was measured here on earth. That this number could be higher outside the heliosphere would, if anything, only strenghten the argument, if i read this article correct.
